Block #4 is so pretty. You only have to make 4 blocks. Remember to use SCANT 1/4" seams on this one. Friend of mine said that she always added a 1/4" extra on outside squares to be assured of having a 12 1/2" block when she squares up. Now, there is one smart lady. For some reason, some 1/4" foots for some machines, do not actually give you a 1/4" seam. BE SURE TO CHECK YOURS! Follow the directions carefully.
