This is an idea I got from Martha Stewart and modified, because I couldn’t find any oil cloth.
Using two contrasting pieces of vinyl, I cut out the main panel (29 1/2″ x 8″) and the two side panels (12 1/4″ x 5″).
It is a simple matter to blanket stitch them all together (because vinyl doesn’t fray).
Then I used pinking shears along the top edge to make them look like the paper lunch bags.It’s a great gift to give to anyone who brown-bags it to work or school, and makes a handy gift bag as well should you want to stuff it with goodies.
