Did you give the sewing machine back to the lady? She put you in a really tough position and I'm so sorry you had to go through that. It really upset me to read that you cried yourself to sleep over her greed. You are a far better person than she ever thinks she could be.
It's now at it's 2nd home and seems to be quite content!
By the way, it's a really beautiful quilt. I love how you put a square on point in the middle of a log cabin.
