Can't say I was thrilled when I saw this month's Seattle MQG BOM assignment was inset circles. But honestly, using the directions by Louise @imfeelincrafty, the blocks went together easily and with little stress.
Louise's Inset Circle Tutorial uses freezer paper, a glue stick, and school glue. There's definitely a bit more that goes into this block design and method than most of the others in the BOM, but it was all definitely worth the effort. I just followed the tutorial one careful step at a time and it all worked out.
