A quilter friend of mine gave me a great hint on washing fabrics and avoided the tangled thread mess. I take my fabrics (one at a time), unfold some if you want, rinse in warm water (no soap) in the kitchen or bathroom sink. Make sure all the fabric gets wet. I usually roll in a towel to get most of the water out, then throw them in the drier and dry. No threads. If they bleed, I just rinse and wring until they stop. My friend and I are both working on Civil Was quilts so we had a lot of fat quarters but I have used this on up to 3 yds and it worked just fine. I then spray with sizing (optional) and iron. Also, they will not be as wrinkled.
