From Prism: "To make multiple freezer paper shapes, I first trace a shape onto freezer paper using a Sharpie permanent marker. Then I layer this on top of 5 other sheets of freezer paper (all of them with waxy side facing down) and iron all around the drawn shape. This holds the 6 layers of freezer paper while I cut around the drawn shape. With this method I get 6 shapes cut out for a single tracing and cutting."
Thank you for this tip. Hadn't heard this one before and can use it!
