The themes of adult coloring books are usually intricate and centered more around adult images, not your childhood counterparts that included bunnies, super heroes, and farm animals. You would expect to see geometric patterns, psychedelic patterns reminiscent of doodle art type pages, fantasy images including angels, dragons, goddesses and mermaids, and ancient designs of religious and spiritual nature.
Coloring is a great way to bond. Ask your friends over for some wine, cheese and coloring. Perhaps at first they might look at you with skeptical eyes and doubt; but hand over a fresh sheet of paper, some vibrant or glitter colored pens and in just minutes you will not be able to pry those colors out of their fingers. Soon you will be visiting easily, looking over at each-others masterpieces from time to time to admire their selection of colors. You will begin to feel like you have time-traveled back into grade 2 and you do not really want to leave. Coloring is freeing and has no expectations. The beautiful thing about this craft is that there is no pressure to finish, to use a certain color or even to stay in the lines!!! There is absolute freedom involved in those precious hours where you just get to color.
