Typewriter Keys Fabric Design

Spoonflower has a themed, "Fabric of the Week" contest, and next week's theme is Numbers. I decided to give it a try to see what other fabric designers think of my ideas. For the contest, I mish-mashed a bunch of typewriter key letters that I found at Dafont. I actually entered a black & white version of the pattern you see above, but I played with several different colorways for my blog. What do you think of it? All opinions welcome! I want to get better at designing for fabric, and the only way to do that is to get your input. :)
