The Nature Printing Society is a wonderful collection of slightly nutty but very well behaved individuals who get together year after year to print fish and plants and anything else that can sit still for just a few minutes.
Their website link is: http://www.natureprintingsociety.info/ and they now have a Facebook page so look them up there too. Exploring the work from past workshops will yield a variety of expertly pulled prints taken from natural things, including an amazing poodle print, (real poodle, like...the dog breed!).
I last went to their workshop in Santa Barbara, California and had a blast. This last workshop was in Fort Collins, Colorado and I learned even more stuff that would have never ocurred to me. Now every time I hike I take a brayer, not really but I feel like I could print "the trail" as I see it and walk by.
Certainly adds a whole new dimension to a printmaker's bag of tools!!!
Here's a sampling of everyone's work showing a wide variety of techniques taught at the workshop:
