Month 5 is done! I used paper piecing, and set the star into the background using Margo's instructions. Here's how I deviated a bit from the method in her video.
I made the background template from 2 sheets of freezer paper ironed together so there was one shiny and one dull side exposed. Instead of marking and hand cutting the circle, I used a circle cutter (left from the days when I thought I was going to do scrap booking
). It cut a much cleaner edge than I could ever do by hand. I did a couple of mockups on cardstock and with scrap fabric to get the size right. The freezer paper template was then ironed to the background fabric, the center cut out, leaving about 1/2 inch seam allowance, clipped to within a few threads of the template, then starched and ironed down. My template was 7 inches square, and I cut the background fabric at 7 1/2 inches, so there would be enough freezer paper to stick it well. I tried to be careful with the starch, but I did end up replacing the template after the 5th block since the edges were getting worn.
