Hi I Steve I suggest you make a "Puppet Bag" of varies sizes and strength! I have 2 large monkeys, and 3 small puppets that I like to carry in a pull along (to heavy) or a garment bag (wrong shape). All I want is a simple light weight black bag to hold 4 puppets.. I can't seem to find one big enough.Would you consider producing them. It might be a product that you customers want??

Go to your local flea market. At larger ones there is usually a vendor with luggage who has black duffle bags. Low cost.
