I'm all for throwing it out if it won't work. But first I'd HAVE to figure out what went wrong and why it won't work! I think quiltmaking is, in a way, problem solving, and that's part of what appeals to me, perhaps....though I admit I get frustrated when things don't work as they should. Maybe it's the pattern and not you.
I certainly understand your disappointment and staying away from that sewing room! But when more time passes you'll feel better and be in there again.
Let us know what you decide to do!
