[Consim-l] DTP: How to make counters?

[Mike NotSpecified]

I have scans of many of my countersheets and comfort myself with the idea that 
I could make replaceemnt counters if I should lose an orginal.

But how do people get quality cunters of the right thickness?  My printer will 
only handle paper up to a certain thickness (read thin), so I presume I'll 
have to glue the printed paper to something, but I've never found the right 
"something".  (I, in fact, have a stack of shirt cardboard and other misc 
shipping materials laying around in case that should be the right answer, but 
even the shirt cardboard is pretty thin, not sure I want to glue up layers)

Anyway, I'm betting somebody already has a slick solution?
