It may be that you are having difficulty with your 1/4" seams because of your injury. I might recommend that you start back with a pattern not requiring so many matching seams. Perhaps use the jelly rolls to make a split rail top. There is absolutely no better medicine than a hit of confidence. And it feels like trying to work thru this problem is creating some frustration. Please do things that will let you give yourself a giant pat on the back to help speed your recovery. Tricky quilt tops can always come later. Good luck to you and keep trudging on - it will get better, just not usually as quickly as we would like.
