So the t-shirt supplier I use sometimes sends freebies with orders. A couple orders ago, I got one of those cinch nylon backpack things. And it needed a classic Jurassic Park logo... because... it just did.
Also, perfect opportunity to test out specialty variety of heat transfer vinyl that works at lower temperatures. It's a little more labor intensive, as it takes prepping the nylon surface with rubbing alcohol and preheating between layers. But the design adhered and the bag didn't melt!
