What are you most proud of? I changed a couple of things. First of all, I took a 2" bite for the corners of the bag, making the bottom wider at 4". I then cut a 4" x 11" piece of quilters template plastic, punched holes in each corner and hand-stitched it to the bottom of the liner. I had to leave a wider opening for turning so this could be pulled through. It just defines the bottom better. Also, instead of just edge-stitching, I used a leaf design on my sewing machine for the edges. What advice would you give someone starting this project? Follow the instructions for your first time. Then play with it. The possibilities are endless.
