I have a really hard time judging how much thread I will use when quilting a quilt. Wendy's quilt is about 100" x 108. so I knew it would take a lot. I wanted to use this variegated teal because there were lots of blues, greens and teals in the quilt, plus the background had some running through it. I thought there was probably enough, but knew I could order some if I needed to. This is what was left on the spool when I finished!
It's hard to tell how much is left on these bobbins, but it's not a lot. Quilting across the row took most of a bobbin, so most of the time I put in a new bobbin at the end of each row. I think I used about 20 bobbins for this quilt.
