WOW ! This challenge has literally caused me to come "Full Circle." Let me explain ! I had an idea set firmly in my mind...Really ! The lyrics to the song "Circles of My Mind" that I sang over and over again, along with beautiful illustrations ! And then I came upon a different illustration of somewhat concentric circles that threw me into an entirely new direction; I decided to just go for it !
Using a new-to-me tool called "The Ultimate Stencil" (www.cindyneedham.com), I traced a number of randomly placed concentric circles onto my all-cotton fabric, then machine stitched around each circle using Madeira Monofilament thread (top thread and bobbin). The circles were great, but the overall effect was BORING ! So I began the labor intensive task of Hand Quilting each of the circles using very thick & heavy, black-core copper metallic thread ... you know... the kind that tangles, frays, snags on itself, and in general takes more time to complete than all the other processes put together ! To help calm-down the thread, I used liberal amounts of "Sewers Aid" that I applied directly to the thread each time I re-threaded my needle. (Sewers Aid is available at most stores that sell fabric & supplies.)
After completing all the hand quilting, I hand-sewed copper beads / buttons to the center of each of the circles. The beads / buttons give the quilt a more finished look, and I think, help emphasize the concentric circles.
For the back of the quilt, I used one of my favorite "Keyhole Binding" techniques, and as you can see, continued the "Circle" theme with my choice of fabrics, and the Circular keyhole.
Peace and Blessings to all !
