Yeah, I bought 2 and they are awesone. Very detailed which keeps my attention. Ive been using colored pencil but I think sharpie would be good on it. Ive got fine print for the small areas.
Im an artist and not used to laying flat color. I usually put shade, shadow, & light to kid's coloring books. But it does keep my attention and Im hoping that it may get me back into my art. I used to sit in a place and draw people before i was terrified they'd hurt me so im hoping to get back there.
But yeah, I had read about adult coloring books all over the site but never thought it would work as well as it does. Im thinking of bringing one to work as I always have to keep my hands busy. Im getting tired of picking the lock I have over and over on a call; now that I can do it in a few seconds. So it would be great at work.
