I bought a terrific layer cake was bought a couple of years ago and it has been “waiting”, along with its solid coordinates, for inspiration to strike.

Future projects are stored in boxes…oops, sometimes for years! (Found a nice set of these at Costco.)
Then the other day I decided I wanted to insert strips of the coordinating colors into the squares. As you probably know, a layer cake is a stack of 10″ x 10″ squares. That means fat quarters (18″ x 22″) of solids will work well for insert strips.
I started by sorting the layer cake squares into stacks with the solids I wanted to use with them.
Then I cut strips of various widths from the solids.The strips varied from 1″ x 18″ to 2″ x 18″, in 1/4″ increments. I cut a variety of widths from each solid color.
I had NO idea what I was going to do with these blocks once I got them modified; I just liked cutting them up and inserting strips–it takes very little to entertain some of us 😉 Then I remembered John Cage’s “prepared piano”. So I called these “prepared fabrics”.
I did the inserts in several ways, still working on this just for fun:
When I looked at my “prepared fabrics” together, it was apparent I wasn’t going to just sew them together along the edges (for several reasons)!
So the next step was to go to EQ (Electric Quilt, a computer program for quilt design) and make some designs:

Option #1. I’ve always loved concentric blocks, and alternating them like this produces a nice design easily.

Option #3. Flying geese are always a lively design element, and I just bought a special ruler for trimming!
What do you think? Anybody have a strong preference for one of these designs? Whatever I do, I think it will be fun to see how the inserted strips turn out in the final design 🙂
