This rug is woven using the simple technique we once used to make potholders on little metal looms in kindergarten. Translation: Anyone can do it! For the more modern rug on this page, we used an all-black warp; all the horizontal loops are from black T-shirts. Then we alternated blue and green tones for the vertical loops. For the rug opposite, we alternated tan and blue for the warp, then mixed up several colors and even stripes on the vertical loops, giving it a more traditional rag rug appeal.
