When I started quilting, I tied them and polyester made a nice fluffy quilt. I personally don't like the shrinkage factor, so polyester was the best choice for me. When I got my short arm, I tried regular polyester. It would catch on the foot. I found Soft N Bright (made by The Warm Company-same company that makes Warm & Natural, etc). Absolutely, love it. It is not made w/resins, it is needle punched. It feels like Warm & Natural, doesn't shrink, and quilts like a dream. I buy 10 yards at a time from JoAnn's with a 50% off coupon. If you are going to use polyester, this is the one. I quilt for several of my SILs and my niece.
