Frequently Asked Questions
Can you print a custom age or milestone number and design?
Yes. Tell us the milestone age — 1st birthday, sweet 16, 30th, 40th, 50th, or any big number — along with your color and design preferences, and we'll create a custom print-ready design built around it.
Can you handle a large family reunion order with many sizes?
Absolutely. We regularly print family reunion orders spanning toddler sizes through adult 3XL, all coordinated in the same design and colors, with no order too large.
Can each shirt have a different name while matching the same design?
Yes. We can print a shared design with each shirt customized with a different name, so everyone matches while still having their own personalized shirt.
What apparel styles are available for kids through adults?
We offer t-shirts, long sleeves, hoodies, and crewnecks in a range of youth and adult sizes, all printed using eco-friendly DTF (Direct-to-Film) transfers that hold up to washing and wear.
How far ahead should we order for a party or reunion?
We recommend ordering at least 2 weeks ahead of your party or reunion to comfortably account for our 5–10 business day turnaround plus shipping time, though we'll always let you know if a rush is possible.
Is there a minimum order for a small birthday group?
No. Whether you need 5 shirts for a small birthday celebration or 50 for a big reunion, there's no minimum order quantity.
