Connie in Colorado does what I do. Plastic canvas can be used for so much more than just making very cool items. I just make a small envelope, slide the canvas in and then when it is time to wash just pop it out and do a gentle soak on the bottom. Amazing how dirty the bottom of our purses get considering the stuff we carry in them. This is discounting the years when my son was a child because then the stuff I carried in my purse was sticky, dirty, gross...
