Adult coloring has really taken off over the past year. It's a great way to release some stress and let out your creative side. Although most of my art projects look like a 4 year old found them and thought "Hey, I should destroy this", it's fun anyway. Personally, I like the way colored pencils look more than crayons or markers. But if you can draw, you are blessed. There are lots of places where you can buy adult coloring books (or kid coloring books, if you're feeling extra young). My mom bought some for me at Ollies, and my aunt got some at Walmart. Coloring is also fun and easy activity to do with kids when you're babysitting.
Anyhoo, it's fun to color anything from complex mandalas to My Little Pony characters. If you haven't already gotten some nice adult coloring books, you should look into it :)
