Cut circles from your fabric and a light-weight interfacing adding the seam allowance. Put them right sides together and stitch the circle shape all the way around. I mark the shape so I can follow along easier. Cut a slit in the back of interfacing and turn Right Side Out.
Use a glue stick to hold in place on the dresden and stitch down.
Do you have the pivot function on your machine? It allows the needle to stay down in the fabric and you can turn the fabric. It may be called something else on other machines.
