I hadn't heard of those before. They seem reasonably priced to try. I have heard of the jelly roll sasher, which I think is over-priced for what it is, but seems to have been made for the rugs. I have not personally tried them, but if they worked and I wanted to make a few rugs I would probably buy one since those are a pain to "tube". The batting really needs to be cut 2 1/4 instead of 2 1/2.
