You’ve done custom t-shirts before. But you’ve probably never seen one do this.
Enter Sun Reveal Ink — the specialty ink that adds a little bit of magic to your next order. Indoors? The design stays hidden in plain sight. Step into sunlight? Full-color art appears right on the shirt like it was waiting for the spotlight.
It's not just a cool trick. It’s the easiest way to take your custom church merch, camp shirts, or mission trip gear to a whole new level. Because let's be honest: your group deserves more than the same old logo on the same old shirt.
1. Send us your design idea (or customize one of our ready-to-go templates).
2. Our team preps your design for print, optimizing it for Sun Reveal Ink magic.
3. You review and approve the final design.
4. We print & ship your shirts within 72 hours of approval.
How does Sun Reveal Ink work?
The ink is UV-reactive. Indoors, the design stays faint or invisible. In sunlight, it fully reveals your printed artwork.
Is Sun Reveal Ink only for white shirts?
Nope! It works best on lighter colors but can be applied to various colors depending on your design.
Can I combine Sun Reveal Ink with other specialty inks?
Absolutely. Many of our customers pair it with Water-Based Ink or even add dimensional flair with Puff Ink.
Is the shirt still comfortable with Sun Reveal Ink?
100%. All prints are done using our Super-Soft Water-Based Ink system, so the shirts stay breathable and soft, not heavy or stiff.

Planning DNOW shirts for your students? Learn how to design custom Disciple Now weekend shirts that build unity and get worn long after the retreat.
A typical Wednesday night shirt has to work for a whole year. A DNOW shirt only has to capture one weekend — which actually gives you more room to make it specific, bold, and a little unexpected.
Because DNOW compresses so much into 48 hours — small groups, worship, teaching, service projects, chaotic van rides — the shirt becomes a shorthand for the whole experience. Students who went through it together wear it like an inside joke.
That's the bar: not just a shirt with your church name on it, but something that instantly means something to the people who were there.
The strongest DNOW shirts usually center on one theme, phrase, or verse — the thing students heard over and over across the weekend's sessions.
Resist the urge to cram in the host home groups, the schedule, or every leader's name. A single strong idea, well designed, beats five small details competing for space.
If you want a fast, proven starting point, Sunday Cool's Customizable Design Templates include options built for retreat and weekend-event use — bold typography, Scripture-led layouts, and graphic styles that are easy to adapt to your specific DNOW theme.
For more on why simple, typography-forward designs tend to outperform busier ones, our post on font-based t-shirt design ideas is worth a look.
Between host home stays, small group sessions, worship, and service projects, students are in their DNOW shirt for a long stretch with very little downtime.
That's why the Super-Soft Tee paired with Super-Soft Ink is the go-to for weekend events like this. The water-based ink soaks into the fabric instead of sitting on top, so the print stays soft and breathable through a weekend that doesn't slow down.
If your DNOW falls somewhere cold, a Super-Soft Hoodie gives students a warm layer for late-night worship or early Sunday morning wrap-up.
DNOW weekends are full of big, emotional moments — a late-night worship set, an unexpected conversation, a group prayer that goes long. Specialty inks are a small way to mirror that energy on the shirt itself.
These aren't required, but they're the kind of detail students notice and talk about.
DNOW runs on host homes and small group leaders, and it's easy to forget them when you're focused on the main student shirt.
A distinct leader or host shirt — same design family, different color — is a small gesture that goes a long way, and it makes leaders easy to spot for students who need help mid-weekend.
A shirt is the centerpiece, but a few small additions can extend the DNOW experience without adding much to the budget — and one of them can do a lot more than just look good.
Woothoop+ is worth a serious look for DNOW specifically. It's the same soft-woven wristband students already love, but with an NFC chip built in — tap a phone to it, and it instantly opens whatever link you've programmed in. For a weekend built around host homes, small groups, and a schedule that changes by the hour, that's genuinely useful:
One tap, no app, no lost link. For more on how it works and other ways ministries are using it, check out our posts on how Woothoop+ works and Woothoop+ use cases for ministry.
Beyond that, a couple of other additions round out the weekend nicely:
DNOW weekends are usually set on the calendar well in advance, but shirt planning tends to get pushed to the back burner behind host home logistics and small group assignments.
A safe timeline: lock in your theme and design 4–6 weeks out, finalize sizes 3–4 weeks out, and place your order with enough runway for Sunday Cool's 72-hour turnaround after art approval to work in your favor, not against a tight deadline.
What makes a good DNOW shirt design?
The best DNOW shirts center on one strong theme or verse from the weekend rather than trying to include every detail — schedule, host homes, leader names — in one design.
What shirt style works best for a DNOW weekend?
The Super-Soft Tee is the standard choice for its comfort and durability across a packed weekend. A Super-Soft Hoodieis a good add for colder DNOW dates.
Should host home leaders get a different shirt?
Many groups give host home leaders and small group leaders a coordinated but distinct shirt so they're easy to identify throughout the weekend.
Can we use tech-enabled merch like Woothoop+ for a DNOW weekend?
Yes — Woothoop+ is a strong fit for DNOW specifically, since it can be programmed to open your schedule, small group signups, or session notes with a simple phone tap.
How far ahead should we plan DNOW shirts?
Aim to lock in your design 4–6 weeks before the event and finalize sizes 3–4 weeks out, giving Sunday Cool's turnaround time room to work in your favor.
A great DNOW shirt becomes shorthand for the whole weekend — the kind of shirt students keep long after the host homes are cleaned up and everyone's caught up on sleep.

Planning a fall retreat? Learn how camp directors can order comfortable, durable retreat shirts that campers keep wearing long after the trip.
Fall retreats are active. Hiking, games, late nights, early mornings, and weather that can swing from warm afternoons to cold nights in the same day.
Your shirt needs to hold up to all of it — which starts with the fabric, not the design.
Most camp directors build their retreat order around the Super-Soft Tee, paired with Super-Soft Ink. Because the ink is water-based and soaks into the fabric instead of sitting on top, the print stays smooth through repeated wear and washing — which matters when a shirt is getting used hard for 2–3 straight days.
For cooler fall temperatures, layering in a Super-Soft Hoodie or Super-Soft Crewneck gives campers something warm to throw on for evening sessions or bonfire nights.
The best retreat shirts hold onto the theme of the weekend without being so detailed that they only make sense to people who were there.
A few things that tend to work well:
If you want a head start rather than building from scratch, Sunday Cool's Customizable Design Templates include options built specifically for camp and retreat use — nature-inspired graphics, bold typography, and vintage badge styles that are proven to work for outdoor events.
Fall retreats are one of the best settings to use specialty inks, because you've got the natural elements to activate them.
These aren't just novelty add-ons. For campers, they turn a shirt into part of the retreat experience itself — something they show each other and remember.
Camp directors often focus entirely on camper shirts and treat staff apparel as an afterthought — but your staff and volunteer team benefit from a coordinated look just as much as campers do.
A distinct staff shirt (same design family, different color or detail) makes your team instantly identifiable to campers and parents, which matters most during check-in, pickup, and any moment where a camper needs to find a leader fast.
Shirts are the anchor, but a few smaller additions can elevate the whole retreat experience without blowing the budget.
For a broader breakdown of how to build out a full merch table, our church merch guide is worth a look.
Fall retreat planning tends to sneak up fast — especially once summer camp wraps and your team barely has time to catch its breath before fall prep starts.
A realistic timeline:
Sunday Cool's 72-hour turnaround after art approval gives you flexibility once the design is locked, but starting the sizing and design process early is what actually protects your timeline.
What's the best shirt for a fall retreat?
The Super-Soft Tee is the most versatile option for retreat weekends, with a Super-Soft Hoodie or Super-Soft Crewneck as a good layering option for cooler fall temperatures.
Should staff and campers wear different shirts?
Many camps use a coordinated but distinct staff design so leaders are easy to identify during check-in, activities, and pickup.
Can specialty inks be used for outdoor retreats?
Yes. Sun Reveal Ink and Water Reveal Ink are popular for fall retreats because they activate naturally during outdoor sessions and water-based activities.
How far in advance should we order fall retreat shirts?
Start locking in your theme and shirt style 6–8 weeks before the retreat, with your final order submitted 3–4 weeks out to build in a safety margin.
Fall retreat shirts don't have to be one more thing on your plate. With the right shirt, the right design, and a little lead time, they can be one of the easiest parts of your planning.

Planning a ministry kickoff event? Learn how custom kickoff shirts build momentum, unify your team, and set the tone for the season ahead.
The first few weeks of a new ministry season shape everything that follows.
A well-designed kickoff shirt does more than mark the date. It gives your team, your volunteers, and your first-time attendees something to physically hold onto — a sign that this season has a direction.
Done right, it:
The mistake we see most often: a kickoff shirt that only makes sense on kickoff night.
The stronger move is designing around the theme, Scripture, or direction your ministry is building toward for the whole season — not just the one event. That way the shirt keeps making sense in October, not just week one.
If you're not starting from a blank page, Sunday Cool's Customizable Design Templates give you a professional starting point built for real ministry use — VBS, retreats, kickoff events, and beyond — that you can adapt to your season's theme in a fraction of the time.
For design inspiration specifically around typography and layout choices that hold up all season, check out our post on font-based t-shirt design ideas.
A kickoff shirt only builds momentum if people actually keep wearing it.
That's why most ministries build their kickoff order around the Super-Soft Tee and Super-Soft Ink — a water-based print that soaks into the fabric instead of sitting on top, so the shirt stays soft and breathable wash after wash.
For leadership teams or a more elevated look at kickoff events, the Super-Soft Crewneck offers a clean, slightly more polished option that still feels like part of the same family.
Kickoff season is also the right moment to think about your leadership and volunteer team specifically — not just students or general attendees.
A distinct but coordinated shirt for leaders (same design family, different color or subtle detail) helps new attendees know exactly who to go to on night one, while still keeping the whole room feeling unified.
This is a good moment to also think ahead: leaders who feel outfitted and prepared show up with more energy — and that energy is contagious on kickoff night.
A kickoff shirt is the anchor, but the best kickoff pushes tend to layer in a few extras that keep the excitement going after night one.
Popular additions for kickoff season:
For a fuller breakdown of how to build a cohesive merch table beyond just the shirt, our church merch guide is a good next stop.
Kickoff dates don't move, so the shirt order shouldn't be the thing holding up your launch.
Start the design conversation 4–6 weeks out if you're going custom, or start with a Customizable Design Template if you're working with a tighter runway. Either way, Sunday Cool's 72-hour turnaround after art approval means the clock really starts once your design is locked — so getting to approval early is the biggest lever you have.
What makes a good ministry kickoff shirt design?
The strongest kickoff shirts connect to the whole season's theme, not just the kickoff event itself — so the design still feels relevant in month two or three.
Should leaders and volunteers wear a different shirt than students?
Many ministries use a coordinated but distinct design for leaders — same color family or design system, with a small difference that makes leaders easy to spot.
How early should we order kickoff shirts?
Start the conversation 4–6 weeks before your kickoff date. A Customizable Design Template can help speed things up if you're on a tighter timeline.
Can we build out our kickoff merch beyond just shirts?
Yes — many ministries pair the kickoff shirt with Sticker Sheets, Lanyards, or Woothoop wristbands to extend the visibility and energy beyond night one.
A great kickoff shirt does more than mark the date — it sets the tone for everything that follows.
