Ok, I thought they were a gimmick. Guess I better put them on my shopping list. I know I could order on line, but what a great reason to go to an out of town quilt show Mother's Day weekend. I hear there is one in Arlington TX that weekend.

I've been using them ever since Sharon Schamber started posting about them on her website. Follow the directions and do take out the tension thingy in the bobbin case. It pops back in if you ever need it. One washer lasts a very long time and it's wafer thin. It stops the static from building up in the bobbin case.
