Until fairly recently, finding colouring books that were not obviously designed for young children was something of a challenge, but they are a little easier to find now. Here are just a few online sources that might give hours of enjoyment:
- Jenean Morrison colouring books
- CT Publishing colouring books
- Art is Fun - there is a free sample page you can download
- Color Pages for Mom - lots of free pages here
Try googling 'colouring books for adults' for titles ... you might find more than you expect, and give you some ideas for age-appropriate gifts.
