I use a feather weight fusible inter facing (Joanns). Cut circles same size as circle templates. Put glue side and right side of fabric together, sew around the edges. clip a slit on the inter facing side, turn right side out. Then I can place on my back ground fabric and iron into place. Then you can stitch into place and have no raw edges. This is how I did the circles on the centers of my Dresdan Plates also. You get a nice crisp rounded edge to your circles.
