MsSage: The resizing isn't that bad. I plan on using this Boston Block method for 12" card tricks. I will be using a 4 1/2" square ruler I have to cut my blocks. Card trick is a 9 patch. Therefore each segment is 4 inches finished to make a 12 inch finished block. I will probably never use anything smaller that a 2 1/2" ruler. I am not into minis. I just recently resized the Carpenter's Star with no y seams down to to a 16" center for a medallion round robing quilt I am involved in. Resizing a block up or down just takes a little time as you look at the divisions in the block and start doing the math. (Don't hate me... I loved math in school. After all I am a retired accountant.) Most come out to nice easy numbers to work with. Block sizes that are divisable by 3 are the easiest for me to work with. I have worked with some nasty numbers.....16ths yuk. So if you see a block you love and want it a different size go for it.
