I am a consultant for a cooking product company. I was given a free apron, but I'm not really the apron type. I decided to turn my apron into a great logo tote bag for carrying extra catalogs around (logo has been blacked out).
It's also a great size for an overnight bag, a reusable grocery bag, etc.
Step 1: Cut Bag Shape
First get an apron, remove the strap(s). Fold the apron in half and cut along fold to get two panels.
If you have pockets, use those as a guide for cutting each square. I folded my pockets in half then cut around them. My panels ended up being 16" tall and about 13" wide. I also used some scrap fabric to make a liner the same size.
