see... i said TONS
So i took one and cut it at the seams and cut a 6" by 10" rectangle like so:
then i added the velcro half and inch from each end and centered. The velcro that is going at the top of your bag should be sewn to the wrong size, and the other piece should be sewn to the right side.
then i folded the bottom part up 4.25" and pinned in place.
then i serged (you can use a zig zag stitch if you dont have a serger) up the two sides and the top.
add some snacks (i perfer raw almonds, nom nom!)
