Ditto what Maine ladybug said. I even opted for the larger 4" size and it was Craaazy. I do know a girl who actually finished hers (one out of 25 or so!) and it is magnificent. Sooooo....I guess there is hope. Someday I vow to finish that bugger!
And I agree with you about their humor. They are truly a great couple. And she is an expert hand quilter who does her own teaching. Definitely take advantage of their classes if you get the chance.
