You have some options for your supplies:
- Of course, you'll need a t-shirt.
- For the stencil you can use: Vellum, card stock, mylar or thin sticker paper
- The pigment can be: Acrylic paint with textile medium, fabric paint or fabric ink
- An iron to heat set your pigment
- Spray on adhesive if your stencil doesn't have it built in
This video will show you how to make your own t-shirts using a stencil, and it's totally entertaining to boot. This hilarious young aspiring comedian will even show you all of the materials that he uses. If you follow the link on Youtube back to this guy's website, you can see clips from his stand-up routines.
And that, my friends, is a pretty amazing instructional video on how to make your own t-shirt using a simple stenciling technique at a low cost.
As always, if you're not into gettin' your hands dirty, upload your designs to Spreadshirt and they'll do it for you.
