If you plan to use 10″ square precuts ensure you have two of each square for the template. 4 10″ squares will only be enough fabric for the bag but you will need additional fabric or ribbon for the drawstring. Another option is to shorten the drawstring to 18″ if that works better for your scraps!
What you need:
Paper and fabric scissors
Pins and/or wonder clips
Safety pin or bodkin
Enough fabric to cover the template
