I know how you feel!
I just had one LAQ'ed that was so flawed by red/white cornerstones that couldn't match up perfectly because the panel fabric's 'rectangles' were off to begin with. I'd loved the panels but wish they'd been consistent with usable measurements! Trying to adjust and match up rows/columns was impossible so the cornerstone problems stand out to me. A non-quilting friend said she really likes it. She's not bothered by 16th - 1/4 inch flaws. Perhaps I'll get over it. I don't even know about donating it to charity because it's disappointing for me. And, to think of what the fabrics cost and the LAQ'ing....
I'll post a picture when the binding's on and ask for some feedback and suggestions.
