First, the parrotmen hut. This could be any primitive hut, really. The base is a $1.00 miniature birdhouse I purchased at a local craft store (Michael's) in their bargain aisle. First I cut the rope loop off the top. Then I cut off the perch in the front and stained the whole thing with a dark walnut stain.
Finally, I used the earth-y looking underside of the pot-toppers I was telling you about in another posting to do the roof. Just make a cone shape by making a circle and then cutting out a quarter of it. Glue to the roof using some PVA (Elmer's) glue painted on pretty thickly. I used superglue to join the edges of the roofing material together. I think it looks like a peat or thatched roof of some sort.
All that is left to do on this one is the small porch/step I am using to replace the perch dowel.
This second piece is an older piece that is getting a facelift. It's gotten a touchup of my now-standard Martian sand, plus a few layers of the water effects stuff I have been using. Finally, I added a lot of reed bundles. These are about an inch tall, so very high reeds/grasses for 15mm, or tall grass for 25/28mm gaming.
[Edit 3/14/11: This is no longer my standard Martian ground. Oh well.]
