I'm looking tomake bags for all three of these and I'm searching for the insulation and outer material to use Perhaps Ill list everthing I find here until I can make a choice. Here are a few possibilities I found at Joann's, unfortunately they do not have weight on them. I'm hoping one of the materials below will be acceptable for weight/durability. I dont like throw away items. The only stipulation for material suggestions I have is to not use material that comes from animals.
