For the first time I decided to count how many bobbins of thread I used. I wondered after reading another quilters updates. She recently uced over 70 on a quilt a little bigger than this one. That sounded like a lot to me, but I had no real idea how many. Well I used 19 bobbins, prewound masterpiece. Bear in mind I think this quilt has quite a lot of quilting. The one the other quilter did may have had 1.5 times the area of mine but even so she has done twice as much quilting! That really is a lot.
