I was given 5 bags of material from a lady whose mother passed away. It had been stored in the attic like forever. Most of it was material for doing over furniture or very heavy drapes. I passed that on. One was a large assortment of solids, which is wonderful. Problem, it had an odor plus extremely dusty. I will wash of, no matter the size, but my question is how to wash it with out all the unraveling and threads. It sure knots up and winds it around each other. Is there a better way of doing it? Yah....all this fabric and I didn't buy it. I don't need more fabrics, but this is a bonus as I always needs solids for fillers.
