If you don't like it the way it is now, you can change it up.
You could put applique shapes in the 5 blocks that look like frames. Also Letters would work ..the word Quilt fits nicely .
The 5 blocks could also be those storage bins with the slide out drawers...you could put quilty words or embellish with fabric, buttons, selvages.
I also like the idea someone gave you about letting the quilting design fill the negative space. I hope you get inspired to finish it...so many ways to change it up! Please show us if you do!
