Still Life

I want to paint a still life and I am going around the house looking for something simple but pretty to paint. There are some little groupings around the pad but I think I will have to compose one just for a painting. Fruit, cloth, a knife...a typical still life, just for practice.
This is one of my current groupings: my mom's glass lamp, an artist's tea bowl with thread, an old watercolor, a box of playing cards and a doll made from a black sweater...
I painted one wall olive green...just for fun, but being that I am in a small space I have kept the rest of the walls pastel. I would love a graffiti wall...
Like a subway wall or something I imagine in New York City, with writing and murals and so on.
