Carpets crochet with recycled yarn

My sister-in-law buys sweaters and afghans at thrift stores, unravells them, then crochets blended colours into carpets in various sizes. There is no pattern, although I have asked her several times for one. She "reads" the project as she works. I've tried to get some shots of the areas of increase in case someone can see a pattern. I just feel like these works of art and love need to be seen. They cost very little in materials, but are precious as gifts from her heart. All of these were on the floor of her home on May 30th. They are washed as needed. Enjoy.
