And now I am starting on the arcs. I picked 6 colors I thought would go together and sewed them with a 1/4 inch seam.
I ironed the seams to one side for strength.
I placed the interfacing on the sewn arc to make sure I am doing it properly.
I didn't sew it in place, I just set it on top to see if the arcs matched up. It looks OK to me!
So now only 115 more arcs to go.
I must be nuts.
