Query: These are the most precious drawings.

I have a large collection of these dover adult coloring books. I must das these illustrations are darling. Being an adult I still can enjoy some fantasy in my life.I recommend these for relaxation. I find that Primsacolor colored pencils work the best for shading and making wonderful creative creations.Highly recommend these books. Amazon had a HUGE collection and the 4 for 3 deal cannot be beat. There are themes just about for any taste.Wahy cheaper than counceling and much more fun. LOL
