I have just spent 2 hours pinning my bow tie quilt on my kitchen floor as suggested by several board members. I have not tried to quilt it yet but it does look tighter than the first time I pinned it.
While crawling around on my knees on the tile floor, I discovered a great quilting tool. Volleyball knee pads. My knees were protesting the project mightily until I thought of using the volleyball knee pads.
