I made this design in high school and had wanted to make t-shirts of it for awhile. I finally made some over the summer and if you want to buy one they are only $15! I don’t have a formal online store, but you can buy one off me in person. If you want to buy one over the internet, message me, we can exchange addresses and info the old fashioned way. The sizes available are Small, Medium and Large.
Update: I will soon put these on eBay but they will be closer to $20.
