Thread Spools Baby Quilt
I won these "thread spool" blocks at our guild's block-of-the-month drawing and made this charity baby quilt with them.
The only marking I did was the smallest circle. I traced a two-inch metal washer with a frixion pen. Each circle after that was made using my walking foot with the guide set at 2 inches from the previous circle. I was able to quilt it in just a few hours.
