Here’s how I sew easy inset circles using freezer paper and glue.
1. Draw a circle onto your freezer paper. Or three if you draw the wrong size. Twice. Not that I would do that. Cut out the circle, leaving the exterior intact.
2. Lay this over the fabric you want in your circle, just to make sure that you’ve cut the circle the correct size. You want to have at least 1/4″ behind the circle for your seam allowance.
