Bluelady is right. I always make my HST a little bigger and cut them down. The pattern calls for 4-7/8" so I make mine 5" or even 5-1/4". That way when I cut them down I know they will be exactly 4-1/2". I measure every "patch" to make sure they all measure correctly before I sew them together. They always turn out right with good points. I made 1 block of each set to see what they look like. I will post pictures in the morning.
