I bought a set at a quilt show and for me turned out to be a waste of $. a set of 3 sizes. normal, tiny and one for the carpet. Doesnt take but a few swipes to cover it, then you have to wash it, wait to dry then do it agai. I just threw the tiny one away the other day and when I come across the normal size its going out too along with the carpet one. There is a reason they are now in the dollar store. I paid $25 for the floor one and the others were a "bonus". If I had bought them at the dollar store I probably wouldnt feel bad about tossing them. I buy the disposable ones in bulk at Costco. I like the idea of having things that dont fill up the landfills,but I also like things that work and last.
