I've seen these cool circular fmq designs so I decided to research them a bit. I kept coming across the word "concentric". Evidently, I missed that day in Algebra or totally spaced it or something. So, after looking it up, I found that a bulls eye is a concentric circle. That will be a cool design to try some day when I have the patience to fish all those beginning and ending strings into the quilt.
I'm quilting giant spirals. I was just winging it, but found that using marking pens helped a lot, especially since I'm quilting this on my regular pfaff with the itty bitty throat space.
