What do you use to stiffen the bottom of a tote/purse?
I am about to make a tote bag for my DD and a purse for an upcoming trip for myself. My question is -- what does everyone use to create a flat, nonbending bottom on their bags? I don't want to put all the work into piecing a nice bag and have it droop.
In the past I have used plastic needlepoint canvas. I've always liked it because you can cut it very precisely to any size, but it is not quite as stiff as I would like. Any ideas?
Many thanks to anyone who cares to share.
