What is some information on fabric painting?

Most good craft stores carry fabric paint. You can get it in squeeze tubes, of jars, it comes in hundreds of colours, five or six different finishes and several systems to "set" the colour.

If that isn't enough there are special mediums you can mix with ordinary craft paints to use on fabric.

I recommend you spend a little time reading the packaging of the various types available in your local craft store and decide from there.
