Last year I had the urge to print my own T-shirt. I couldn't find photo emulsion locally and I didn't want to pay to have a large quantity shipped. Instead, I made a stencil (with an island) as a cheap substitute.
Yes, that's a check engine light. I now own a VW and was told that I'd have check engine lights every 1000 miles.... It's been a little bit less than 10,000 miles now... no light. I'm still amused by the low washer fluid light and alarm :)
My apologies for the low quality pictures....
Step 1: Tools and Materials
Contact Paper (the stuff with a sticky back) -- shelf paper works too.
A bit of cardboard or plastic or something to prevent the paint from bleeding through the back
Something to push paint around evenly (a scrip bit of cardboard will work)
Razor knife and cutting board
