Step 6: Add Padding
Turn the bag inside out and sew a seam one inch from the edge (still not sewing on the open side)
Seam a seam 2 inches from the bottom, or the short side that is sewed closed
Take out the extra plastic bits from Step 2, the used wax paper and more plastic bags and begin stuffing the case. When you get about 4 inches up, seam another seam across the case.
Stuff more and seam until you reach 6 inches from the top.
