Someone posted a link fro an appliqué Craftsy class last week. The instructor cut a cardboard circle template, laid that on top of wrong side of fabric, put a piece of tin foil under the fabric and scrunched the foil up to get the circle ready to iron. It looked like a nifty way to get a perfect circle.
Using the running stitch around a cardboard template method works but the foil sounds a lot easier. You can cut away the background under the circle after you appliqué it down especially if you have more layers to add on top. Raw edge appliqué circles are nice too for a different look. [/QUOTE]
