This is a down-and-dirty quick apron that you can make en-masse for various messy projects. I came up with it in the first place for a paper marbling class that I was teaching last year. The size of the apron can be adjusted to fit smaller people, and if a strap breaks, the fix is no farther than the "Handyman's best friend." ;)
This instructable was inspired by all of the great apron instructables already on this site, specifically the apron made out of a plastic tablecloth,
and the no sew duct tape apron.
Step 1: Cut yer plastic.
Cut it out.
