Here is a list of all of the materials that you will need.
6 yards denim or scrap blue jeans
6 yards of your choice of fabric for back (I used flannel cut from an old shirt)
Denim needles (also called jean needles)
Before you get started, make sure that your sewing machine is threaded correctly and that you have tried the thread and stitching on scrap pieces. Easier to make a mistake on scrap and the fix than to try to fix the pieces that you are actually going to use.
