I cut them in quarters, to create each side, and lining of the bag. I used scraps of fabric at the top of one side and for the handles. Everyone loved them. The kids are using them now when they grocery shop and will use them at farmers markets this summer. Their size is 18''x23''. So they will hold a lot. They are also strong and very washable. I thinks it's a great way to re purpose the bags.
Enjoy your day,
