Lynnie, the widest part of these stars is 13-1/2" unfinished. The pattern on the freebie I cut from a bit more than 4" wide pieces to give me room to cut an even edge, and the longest measurement was 7-3/4"I have ordered a template online, it has lines to make smaller sizes, I think it was 1 to 5 inches.
And yes, nativetexan, they were sewed in rows. Went together rather quickly after all the half blocks were up on the design wall.
