Mr. Steamy balls really work! Last night I dried a shawl I just finished, made from acrylic yarn. I had another shawl and a sweater, both made from acrylic yarn that I threw in with it to wash and dry. I didn't use fabric softener and there was no static, everything came out soft. I thought I'd mention it in case others who use synthetics would like to skip the fabric softener or at least use less. I'd used them in other dryer loads but this was the first with all acrylics. I'm surprised they worked.
This is the last time I'm frogging this project for the last time.
