I was amazed at all the possible looks and variations but settled on a chevron pattern as Chevrons are striking and allow for a diversity of quilting in the white spaces. I use "paper" (by 53) or SketchbookPro for quick sketching and practicing my longarm quilting motions (similar but easier than an Etch A Sketch!) and I can store them easier than paper.
I used a green Minky backing and Marcia Derse's Mosaic 10" squares (Windham) for the top (cotton fabric).
I free motion quilted it on my non-stitch regulated Sweet16 that I am able to move to this great 6 foot ArtQuilter frame I bought from Martha (http://www.machinequilter.co.uk) in 2011. It's a great frame and it's portable. Takes less than a half hour to set it up on any six foot table. Great for art or baby quilts. But, it's not big enough for stuff I want to do three years later. Should have bought the bigger one!
In the white spaces the design is a loose flower motif at each point and straight lines in between. On the chevron itself I chose to use a meandering stipple. I was traveling way too fast for the speed of my needle and although the stitches are pretty regular I found a few eyelashes on the rounded corners.....lesson learned :-).
I think it turned out quite nice!
