New Incentive to Quilt More

Just can't seem to get my next sweater going. It is the same pattern I made last time, which went together so fast. I have started over once and spent hours last night tinking (knit spelled backwards) and am still off. Why oh why didn't I count the stitches sooner? Without the re-do's, the sweater would be almost done. I unraveled 6 inches the first time and around 3 inches this time and I still haven't found the mistake. It is probably going to be a long time before I pick it back up which is great incentive to jump back into quilting.
