Several people have asked me about the size. These blocks measure 12.50". The bonnet girls measure approx. around 9.50." I haven't used any of the patterns from the books yet. The individual patterns are huge...I believe most of them measure for a block approx. 22" x 30." That's much larger than I would like..So, have had to make adjustments. When I use a pattern from the book, will have to resize again, for them to measure about the same size as the individual patterns, because I want them all to be about the same size. Hope this helps...I didn't realize how huge the individual patterns are..
