I usually don't purchase fat quarters, usually cut them on my own.
But, they are useful for making a set of potholder hotpad fabric trivets, or a waist style apron. You will still need the Insulbrite for the potholders, and the apron waist part and ties for the apron, but it does save a little bit of time if you want to make something quick. from, Debbie, Phoenix, AZ
