Keep working on it while working on another project. Allow yourself 1 hour or set a goal say 2 sections of a block a day. I have been working on a quilt and didn't know why my back and arms ached. Then I realized it was the pulling and tugging of the quilt as I stitched straight lines in the sashing squares. So now I give myself a goal instead of spending 6 hours on tugging and shoving. Your quilt will be stunning when done.
