Adult Coloring-Knitting Style

I have always loved coloring and especially with my Prismacolors.  Recently, the adult coloring books have taken the book market by storm.  I have been really intrigued by these, and almost added them on to my Christmas list.

Then, I saw these versions for knitters:

How much better for a knitter!

I just placed my own Christmas order for these.  Looking forward to some coloring time!
