Large roll is on a cardboard tube from JoAnn's - stands in corner behind door in sewing room.
Smaller pieces get folded or rolled, stuffed into vacuum seal bag, air sucked out with vacuum sealer, sealed & size marked on edge of bag. Perhaps it should be allowed to 'breathe', but this works for me & cuts some of the of volume batting space would occupy. I use my vacuum sealer for many things in addition to freezing wild game. :+)
