Rob wanted to build up the canyon walls beside the stream on Barbara’s HO layout, once again using left over building materials.
Cutting and bending some old fence wire for support, he attached torn sections of leftover blown foam insulation. Leftover wire from securing rebar for the house foundation pour was used to secure the foam to the framework while the glue set up.

While detailing and painting may consume a lot of time, this intial construction went very quickly. The result reminds me of the structures in some Disneyland rides – puffy and cloud-like. Of course, they may look very different when finished.
