You will need:
Your choice of fabric for the bag (I used a jersey knit material)
Various fabric scraps
Step One: Cut the fabric you are using for the bag to the size you want the bag to be. Leave about 1/2 inch seam allowance. Then take one of your fabric scraps and cut it in a strip long enough to go across the bag with a little excess.
Step Three: Using a zig zag stitch sew all the strips on. I set the horizontal spacing to 0.5 and the vertical to 3.0. This will give you a thick applique finish. This will take quite a bit more thread. It will also take more time.
