This is only if you have the budget.
If you found an awesome design (picture, font, drawing, etc) you would love to use during your event, don't forget to check the license! Only use open source materials or pay for the license. If you can't find the license of something, please don't use it.
This is so far the most fun and most affordable way to do something nice at your event. You only need to buy Temporary Tattoo Paper, print our ready-to-go designs on your home printer, cut them out and you're good to go! You can get a lot of tattoos for just a couple of bucks.
T-shirts for coaches
Order t-shirts for your coaches as a thank-you gift, but wearing the t-shirts also makes your coaches more visible in the venue. You can find t-shirt designs on our resources page.
We like tote bags, right? They are pretty cheap to print and it's a nice gift for your attendees that will remind them about the event later on. You can find designs on our resources page
