I bought an adult coloring book in spite of the advertisement saying it would make an heirloom treasure. Good grief. I guess I like it. The first one was abstract crystals. I colored a few of the pictures and decided I'd rather have flowers. But I had to buy what I could find and got fantasy animals. I like it better than the abstract crystals. I went to get a pencil sharpener for the colored pencils I was using and found twistable colored pencils by crayola. They are kind of like mechanical pencils so they don't need a sharpener.
