I just came in from finishing a rag rug. I really liked the method for joining my strips. I showed it in a previous post, as I decided to try it. I did move the sewing over to my industrial Singer 111, because it sews faster. If anyone tries this method, just make sure the fabric joins are staggered. I overlap my joins about 1". The join won't pull apart, because it has a solid strip backing it. I was using a lot of doll clothes scraps, so some of the strips were short. My strips varied anywhere from 6" to full fabric width. To avoid stripes in the rug with the longer strips, just flip it over in the shed to have the reverse side show. I used a neutral sewing thread down the center of the strips, wrong sides together, and the thread doesn't show in the rug.
Here is the hem end, with glue. I will let it dry overnight and probably cut it off tomorrow and get it hemmed. The colors in this photo don't show the green very well. All the fabrics that I used had some green in the pattern.
