Just finishe making a drunkard's path quilt with baticks. I don't pin except when I start.
I sew one inch from the bottom. Stop. And then sew one inch starting at the top working my way to where the bottom is. I do place my fabric the way they show in the above mentioned video.
Sew slowly and stretch the top part...the pie not the crust...so it with fits the curve. Never a problem with the edges matching.
Have the curve master but never use it.
Works like a charm!!
