Shaping a bag - sewing texon/bontex

[Wepster]

just musing, I wonder how cork "leather" would work as a stiffener?

Anything can be used as a stiffener or a stay. It all depends on the look you are after and the quality of your product. For example, you can use the cereal box, but it will not hold up. Felt, foam, leather, bontex/texon, interfacing, etc. can be used and work well depending on application. Sometimes the look you want will dictate the stay, but it might require a different approach to construction as well.
