This wonderful tip and bonus a tutorial comes from the blog Rosey Corner Creations. On this post she shows how to make 2 versions of a cute little vinyl card wallet.
She also gives a great tip about sewing on vinyl. Which is so annoying because the presser foot gets all hung up on the vinyl but the fabric sews fine and you end up with a mess! She shows the cheapest, easiest method ever.... Scotch Tape!
