Thanks to all of you for your thoughtful, helpful replies. That's why I posted. I know I can always count on help and comfort from the wonderful quilters on this board! A day has passed and I feel better. I'll have to do some ripping and resewing, but I'll eventually get it right. The pattern I'm doing is Spaghetti Junction by Heather Mulder Peterson and I'd post a link but I don't know how to do that. Anyway, I have to match up some narrow strips from block to block so just squaring up won't work. The problem is my lack of a consistent seam allowance. Somewhere along the way I started sewing a scant (very) quarter inch as opposed to just a quarter inch. I could kick myself. Why would I do that?! If I'd just stayed consistent I'd have been fine. Another lesson learned. In the future, I hope I'll remember to measure my units and stay consistent. I need advice now on a substitute hand work project, but will make another post for that. Thanks again!
