I cut the paper circle from two thick layers of freezer paper and ironed it to the fabric. I then ironed the outside seam allowance after starching it. After that was done, I cut out the excess fabric from the center and did the same to the inside seam. I'm using a hard pressing board I made from an Ikea lazy susan and thick linen fabric.
There's a lot of information regarding the starch and iron method on you tube from Simple Bird Applique (click) if you're interested. It suits me at the moment as the stitching seems to go faster and its not as hard on my weakened right hand. I also like to use the Clover mini iron.
