I published my first colouring book called 'Cats, Birds and a Rabbit: Colouring book' last year. It contains a collection of some of my illustrations which I though may be enjoyable to colour in. It's available at lulu.com , good book stores like amazon and Barnes and Noble and directly from my colouryourgift.co.uk online store.
Publishing my first ever colouring book was great fun and a nice accomplishment too. I've learned a lot during this process and must say that lulu was definitely a great place to self-publish my first book.
I've included photographs of some of the pages inside to give you an idea of what you get to colour in.
