You will find making your patterns to cast the parts to be fun, at least I do.
Follow the myfordboy link posted previous, he has a ton of good info, and has no blabbering while making his videos.
It makes them much more enjoyable to watch
Here's another forum you may find helpful- all about casting stuff!
