Well... After laughing and agreeing with most of the wrongdoings, I canshare a couple I didn't see or missed: when I am too anxious to finish a quilt, I sandwich it and use 505 instead of pins, so when I quilt it, the fabric fokds underneath because I didn't do a good job. Oh well, I quilt over the fold to hide it!
If I left too much of selvage and the white shows.... I use a permanent marker.
Last, if the seams don't lay to the right side, I make a cut near the seam and iron it to the "right" side
Lol- all the other "quilt police" no no, have been mentioned!
