Question: What is the easiest circle and oval circle to use?
Answer: We have several circle cutters. My favorite is the Circle Cutter from Fiskars. It is the one with the large orange button on top that you press to hold the center of your circle in place. Besides just a template/guide that you can use with a blade pen, the one from Fiskars is the easiest I have used. I don’t personally have an oval cutter, but I would trust the one from Fiskars as well.
