Such a good question! I am waiting to see all the great responses here too. I am thinking about ordering those bag e bottoms, but they seem pricey.

Plastic canvas-sewn in under the lining. Or the dollar store's, bendable cutting mats- 2 per package. Just cut them to size. It depends on how stiff I want the bottom to be.

I get scrap plastic sign material at the local sign shop.

I use plastic canvas and cover it in fabric. I leave an opening so I can remove the plastic when I wash the purse or tote. If it's a big tote for something like groceries, I don't put anything in the bottom, just box the seams.

thats what I do too.

I just use matte board.

I've used them, but I move them from bag to bag. I don't make a cover for them, just put them in whatever I'm using that day.
