thanks...
would something like this work though?
Professional Grade Screen Printing Units - BLICK art materials
if i make sure that when im exposing the two seperate screens that the designs line up exactly, then i can just put the first color on, take that screen out and then put the other screen in and do the second color
this is probably gonna be a one time thing and it's a run of only 25, so the ryonet is a bit out of my price range for right now, and i don't really have the time to build one.
