This page is hosted by animanga, but was written 
by Kenneth Allred. It is a very clear list of the 
materials needed and basic process of framing. If 
anything, it's a helpful checklist of things to 
ask the frame shop. There are also a few links at 
the end of the page that go into more depth. 
Here's the link (above as well)
