I do not know if this has been mentioned before or not. I was trying to think of something cheap to put in the bottom of the purses that would not "melt" if it got wet.
I went to Lowe's and bought plexiglass. For a 18x24 piece it was $8 and they will cut it to size for you. I got 8 bottoms out of that 1 sheet. They are 4 1/2 x 12 for the mini bow tucks.
Just thought I would share!!!
