Thank you all for the most excellent information. After reading everything and looking at the links, there does not seem to be a specific term, then, to differentiate between the two types of se-tenants (ones that the design can stand alone and ones where you separate the design when the stamps are torn apart.)
What I was thinking, was that when a beginner finds a single stamp from the space set posted above, he knows immediately that that there is something "going on" because there only 3 white edges.
If he found one of the "The National Postal Museum" stamps by itself, he would never know it was a se-tenant unless he happened to look it up.
I guess I am just nit-picking now, lol. I want to make sure I've done enough research before this upcoming scout workshop. This will be the second one I've done and it will be in a different city with strangers (who happen to be scout stamp collectors) helping out. I'm starting to get nervous about the whole thing!
