Yes, I have an underwear collection. I have finally figured out what to do with them. Inspired by our rag rug weaving project at work, I am braiding the underwear. My first thought is to make a little matt, but it might also turn into a picture frame. The rag rug process welcomes the castoffs, including synthetics. We can use all clothing that cannot be donated with dignity, says our loominous weaving instructor, Corrina Hammond.
