I couldn't find the thread David started. I have this neat tool to close the pins when sandwiching a quilt. I coudn't do without it.
It is the Kwik Klip- Paula Joan Creations- Sacramento, CA (916) 468-3480. I had it years ago, I haven't seen it in the quilt store anymore.
Once I went to a class and a quilter had one made with a wood handle and a screw. Worked just fine.
