Step 1: Stuff you'll need
3. Roland Versacamm printer
4. Vinyl sticker paper (you can get giant rolls online or smaller home use kinds from craft stores)
6. A computer
You can also do this with photographs or draw directly on sticker paper without having to touch a computer. This is a good option for one-time production. If you are wanting to reproduce -- in case stickers wear off or get pickle juice accidentally spilled on them -- having the option of reprinting might be appealing.
