I designed these shopping bags to be easy to sew and fun to use. They are fully lined and can be cut out of a 40-inch-wide piece of fabric. This means they will fit on most quilting cottons, even if the yardage shrank a bit during prewashing. These bags only require 1.3 yards of fabric if both lining and fabric are the same, or 2/3 of a yard of each fabric if they are different. You may find it easier to keep track of which layer is the lining and which is the outer bag if you use contrasting fabrics for your first few bags. Have you heard of the burrito method, but aren't sure you want to try it on a garment? I included step-by-step photos for using it, so this is a great first project to try that technique!
