Another Winter project and a warning.
A few years ago I scrounged some sheets of decorative indoor flooring. I cut these up to make parts for roofs, nucs and bait hives. It turned out a bad idea. The material was a coated highly compressed cardboard. The board has absorbed water, swelled and become heavier.
I intend replacing the parts with some thin T & G timber. Scrounged again. Ain't I cheap ?
