Coming from someone who has not been doing this long, I'm perplexed. I just don't get it. I saw some on Craftsy or Groupon or whatever that were on sale for now only. When I calculated the yardage, it was not a "real" deal. Even though they were like 40% off. Then I noticed they were advertised for 5.5 inch squares, but they had a shear cut (zig zag) so I was wondering: Is the 5.5 inches measured from the outer point or the inner point? And, how functional is it, if you just want to sew squares together? I can't imagine not having a straight line when I sew squares together. I would never be able to discern a quarter inch seam!!!
Anyway, leave me some insight into this in the comments. Remember, I'm just an amateur.
