Coloring Book Anyone?

I don't know if anyone else has noticed this but I am seeing coloring books for grown-ups everywhere! (I wanted to say adult coloring book in that last sentence but I figured out that might be misinterpreted)

Anyway, I thought maybe I could do a coloring book of my quilting designs. The picture above is basically a reinterpretation of My Tweets block 1. You can see the original below.

What do you think?
