1. Buy yourself a (white) T-shirt $5 to $10
2. Copy the T-shirt design from the website onto a CD or USB stick
3. Take the T-shirt and the CD/USB stick to a T-shirt printer and ask for a “digital transfer”. The cost will be somewhere between $25 qnd $35. If you can get a group, you may get it slightly cheaper.
4. Wear the T-shirt as often as possible
