I have several old cashmere sweaters that have seen better days, and I'd like to recycle them by fulling and using the fabric for projects. I have a front loading washer that is really gentle on clothes. I washed a light blue sweater using the hot cycle with detergent and a pair of jeans. Not much fulling occurred. I don't know if it was my washer or the fibers, which probably had been bleached before dyeing.
Does anyone have any advice about fulling cashmere? I've heard of putting a tennis ball in the wash, putting the sweater in a zippered pillow case, and drastic temperature change. I don't know if I can achieve drastic temp change in my washer. I've also heard of using a clean plunger in the sink. Does anyone have any experience with these approaches, or have any other suggestions?
TIA
