The listing, Aunt Philly's Toothbrush Rugs Instruction Book and Tool ~ NO SEWING REQUIRED has ended.
"The "Toothbrush Rug" technique is a fast and easy way to turn torn strips of fabric into a beautiful rug."
No sewing is required. http://www.auntphillys.com/ (very, very short video showing what you can make with the instructions).
"All fabric is laundered before you make the rug so it is machine washable, dryable and lasts for years. The rug is reversible, so turn it over when the one side is dirty, and use the other side before you launder it."
This auction includes the booklet for making square or rectangle rugs and toothbrush tool. If you start now, you can get some made for your spring and summer craft fairs, or even next Christmas giving!
And I imagine you could make things other than rugs also...
The pattern book retails for $10.00 + shipping on Aunt Philly's site, and the toothbrush tool for $3.00 (although they say you can make your own tool out of a toothbrush like they did in the old days!).
I have so many pieces of fabric, I thought I would do this, but I have had this for about 10 years, and have come to realize that I'm probably never going to get around to it.
If you have a lot of fabric scraps, this may be the project for you! The creator of these patterns says she can make one in a day (she is more organized than I am). :)
