I tried the English paper piecing way and also have the Stamps by Kate for a hexagon. I decided to try to sew on the sewing machine.
I started 1/4" from each angle and stopped 1/4" from the end of the angle. It works like a charm!! Once I complete a flower, I take it to the ironing board and press the sewn seams in one direction.
Go to You Tube and search for "how to sew a hexagon Grandmothers Flower garden on a sewing machine." Hope this helps!!
