Ruler for half hexagon?
I am making a one block wonder and I know that you sew three triangles together first and then attach them by rows. HOWEVER, I always like to make sure that I've got accuracy, so the question is, does a ruler exist where you can "square up" half of the hexi prior to sewing the half-hexi's first? Or do I need to not worry about accuracy with this one? Should I just chill?
Thanks in advance.
