Colouring in books for adults.

The term 'adult colouring books' always makes me smile, as people who don't know about them sometimes raise their eyebrows, thinking this could be some kind of pornographic material!  But of course it is not, I have been buying colouring books for a few years now, but it is only very recently that the idea of adults "colouring in" like we all did as kids, has taken off in a big way.  It's mostly to do with relaxation and stress relief therapy, although I don't look at it that way.  Being a bit on the artistic side, I just love painting and colouring in for its own sake!
I bought these today at the Craft & Quilt Fair, and will post photos of the other ones in my collection later.
