Canvas or muslin fabric (I purchased at Wal-mart for $1.97 a yard)
Drawstring (I purchased from Home Depot for $3.50)
First, I cut my fabric 28" by 17" to accommodate a men's size 11 shoes. Next, I ironed a 1/2 inch seam on the long side of the fabric which will become your drawstring seam. Then design your bags as you wish. I used fabric markers and stencils because I always need a template. After they are designed and dry, fold the outside (where you designed) into each side to create a 14" by 17" bag and stitch the two raw edges. Flip to the correct side and insert your drawstring with a safety pin.
Ta-da! You're done.
