Krystyna,
I've had a quick look at your secret picture and think you've missed something. If you look very carefully at the bottom left hand corner of the backing, about a quarter of an inch from the edge, you might have to squint a bit for this, but the black and white runs into copperplate script and it says "Krystyna made me this way so I must be OK"
You haven't seen my quilting yet. Relax. Yours is way ahead. I just fudge my way through. Also, when the picture of my quilt to Grammy6 goes up I'll send you a PM telling you all about the dodgy binding, and you'll feel even better.
