How to sew

I always wanted to learn how to sew, but for some reason never took the time. Now that I'm looking for a baby mobile, I can't seem to find the 'right' one. I don't like the awful harsh colours, the plastic one's or some of the figures on it.
I want it to be about nature, with natural warm colours. Lovely animals to look at. So, I'm thinking about getting it done myself. With a little help from books and my mum, I think I have a good change to succeed.
