I've added a couple dandelions out front. I hand cut the leaves and calyx from painted coffee filter paper. The yellow flowers are simply mounds of glue covered in flocking. For the dandelions gone to seed, I used a clear bead covered in a fine layer of white flocking.
I made a second dandelion half hidden behind the boot scraper. This one had a bit of wanderlust. I'd actually glued the plant down in another spot, and had to "dig" it back up when I realized it was nearly in the walkway.
I was considering adding some litter to the sidewalk. I went so far as to make cigarette butts, but I ultimately decided against them. I went to college with a lot of smokers, though I'm not one myself. This tattered old flyer is the only bit of litter that made it onto the shop.
I did add a few more washes of "dirt" to the sidewalk. I was pretty pleased with the sidewalk stones, but they were starting to look too clean and new amidst the rest of the scene.
I also finished the iron fence on the left side of the scene. I had a bit of a happy accident with the fence. The iron paint dripped and formed rust stains on the stones.
Last of all, did you spot the new addition to the rose bush? This little nest was an experiment that turned out even better than I'd hoped! Most of the miniature nests I've seen looked really fake. A few weeks ago, I cut a handful of dead winter grass and spread it out over the radiator. Once it had dried out really well, I crumbled it up, and mixed in a drop of tacky glue. The grass and glue mixture formed a quick-drying clay, which was easily sculpted into a nest.
