It is imperative that we stop using single use plastic bags. I am selling reusable bags made from denim jeans on Etsy. They are $25.00 each but if you give me the jeans to use, it’s only $15.00. It’s a great deal. These bags are fabulous and will serve you well for years.
If you are a sewer, here are the directions to make one for yourself:

Cut one piece from the waistband down that includes a pocket. Piece from the extras to make it 20″ in length.

Center pocket. Stitch along bottom. Stitch a triangle into each side of bottom. Add handles and a label.
