HI, I use batting, Warm and Natural. I use either a straight pc for sides and bottom or I use squares. It is easier to use the straight pc.
I use Timtex in the bottome to stiffen the bottoms. It is an iorn on material used to make fabric bowls.
I make the zipper pocket and attach to each side on the inside. Makes for larger pocket and 2 slots on each side.
If forgot anything, lol ask again
