They make great covers for my 3 x 6 brooder/tractor. Newest brain storm: cut them into appropriate sized pieces, and use them to stuff "sock babies" for the puppy. She loves her sock babies stuffed with water bottles. They make a very satisfying crunchy sound, but she chews through them at the mouth of the bottle. I think the crinkly feed bags will last a bit longer. I may make some babies out of feed bag stuffing with some tougher duck or canvas type of material for a cover.
