Judy, according to Lesley's figures, you will need to enlarge by 142% for a 10" block. I haven't tried printing mine out yet...I'm planning on doing it tomorrow. I'll probably copy, slide it over, copy again, cut and tape the pattern together to get it all on one page.
Gai, your friend's idea sounds really pretty. Will she join the QB so she can post pics on our threads and play with us?
