Thank you all for the advice and encouragement - and sympathy for the pattern-challenged LOL.
I like the idea of one little mistake hiding in a quilt - I would never have to do it on purpose. But this quilt center is one of those big-print things with only 13 blocks plus the setting triangles.
I knew I should have gone to the office and gotten a bunch of those arrow 'sign here' stickies but I was soooo sure I could do an on-point quilt without getting up and down mixed up.
I will take a deep calming breath, and slooowwwwlllly and carefully pull out the stitches without gouging the fabric, re-press, heavily starch the surrounding triangles, pin and sew. Right side out, right side up, I hope.
Wierdly, once there is a mistake, it sometimes seems to become the source of another mistake, doesn't it?
Thanks again all :thumbup: :thumbup: :thumbup:
