I love the idea of a mystery quilt. I found one for a friend and I to do. I thought it would be a great way for us to get together. I intended to print out each month at a time to work through it. She wanted them all, so I printed them for her, and she promptly showed me how she had completed so many of them. I told her over and over I did not want to see what the next blocks were. She pretty much "forced" me to see them by showing the ones she had completed. The last time we got together she had them all done and said she would show me her completed top the next day. Again, I told her I do NOT want to see it.
I set my blocks aside, and will complete them in my own time, still intending to see the "surprise".
Oh, wait, this isn't about me...... lol. Yes, I think mystery blocks are fun!
