One of the first accessories I wanted for the dollhouse was a stack of miniature firewood for the front porch.
For the holder, I took a piece of coated copper from a section of wiring that was leftover from our real house renovations, and bent it into a rectangle, then curled the ends of the rectangle up to cradle the firewood. The firewood is just a twig from the yard, broken it into one inch pieces and hot glued together in a pile.
There are some awesome firewood holders available online, but this will do for now. Especially since it was free.
