Most people have a cross somewhere in their house, be it a crucifix, a bible, or just a simple cross on a chain. Naturally a small cross on a chain is going to be a bit harder to work with, but just about any other cross you may have could be used to determine a simple ratio to start with. You could also try to download a simple pattern from one of the free MSN sites to use as a template. Other than that I have no idea.
