I work on string quilts in the middle of the night when my ankles hurt and I can't sleep. I found it more tedius when I had a set number that had to be completed and it seemed to take forever. Plus only using neutrals seemed to make it more tedius to stitch them.
When my late husband was ill and having trouble sleeping, I made 3 Christmas string quilts. They seemed to go faster because I didn't have a time limit and I just worked on them when I wanted to.
