Human: I need to know how to make my own reusable grocery bags. Assistant: 
Making your own reusable grocery bags is easy! All you need is fabric, scissors and a sewing machine or needle and thread. Cut out two rectangles of fabric that are slightly larger than the size of your grocery bag. Sew the sides together using an overcast stitch (sew the edges together with a straight stitch first). Turn the bag inside out and hem the top and bottom edges with a zig zag stitch or serger. Finally, add a handle if desired.
