Nothing too exciting. I just mounted them to thin cardboard with hot glue and coated them in 50% pva, 25% black paint, and 25% water before painting them. I can post the paint I used if you want to get the effect on the rocks just let me know. The only twist with these is that when I got the pine nuggets they were damp so I dried them in the oven and it created all sorts of interesting splits and cracks in them.

Neat! I especially like the blue ones. Never figured bark could look so much like stone.

Bark is one of the classic materials for rocks, they do take a bit of work to get to a tabletop useful state, but can be used for a lot of things.
Want to make some cliffs, you can mount bark chips on foam to make a far more realistic appearance for cliffs, and smaller pieces work well for broken ground.
However, for those wanting to use it, as vepr did, bake it in the oven high enough that it kills any mould or other things in it (Wrap in foil, stick it in at a decent temp until you get a bit of smoke), then freeze it (Leave it in the foil and let it cool to near room temp first). Seal it with watered down white glue when you have it in position and again when you're done painting or hit it with varnish.
Bark is a great thing to use, but the downside is that it is brittle and fractures easily. Now that's useful in shaping it for some uses (because the fractures look like exposed rock) and a nightmare for others (If you don't seal it, you might have your terrain self destruct on you with normal use in a short time).

I worked woth bark a bit before, but I never figured out that bark should be heat- and cold-treated before use. So thanks for the heads-up!

Agreed, bark is superb for shapes, and textures. Also agree with the comments about it being biological material, and subject to becoming a biohazardous material unless it is properly sterilized. Did not know about the best sealing methods, though. They look gorgeous. Hope you properly cured them before painting. Cheers!
