Grungeboard or Grungepaper

OK, I'll admit it.

I don't know the difference between grungeboard and grungepaper.

For Grungy Monday 16 we get to use either one.

So I did, with whichever one I used.

You know of course that both

Grungepaper and Grungeboard

are created by the talented

Tim Holtz.

And where do you find Grungy Monday?

Well, that's here
