Wandering around Home Depot or Lowes is almost as fun to me as the fabric store! (operative word :ALMOST! lol) I found a blank sign- like you might put out front of your house for sale. It is like a corrigated plastic and easily cut with a utility knife. I used it for the bottom of a new tote I made and I love its sturdy lightweight base. Here are pictures of it being cut. The piece was about $5 and I will get about 5 purses or totes, depending on the size. I did cover mine to match, but I dont' think I needed to. I also cut the 'ribs' of the plastic the short way. I am hoping it is a sturdier cut.
