I finally decided how to quilt Rock Candy. I decided to make an FMQ loop that would fill in the diamond shape. I also outlined each diamond.
It's easy to see my FMQ on some of the darker diamonds. I'm using Aurfil 50wt thread in gray. Bottom Line, in a silver color, is being used in the bobbin.
This next picture is even closer.
I didn't have to outline each diamond. If I didn't outline each diamond, I would have to cut thread each time I quilted inside the diamond. I could easily travel from one diamond to another using the outlined seams.
Now, I have to figure out what to do with the small border around the diamonds.
