Long time readers will know that I had a big change of heart a few years ago. Beforehand I'd shunned Wills sheet for being too much faff. Then I was given a Craftsman kit and thought it rude not to build it. Result: I now rarely use anything else for buildings. Result 2: There are off cuts. They are thrown into an ice cream tub which is good, but not good for finding anything specific. This morning I needed some brick sheet, but couldn't find anything suitable at the top, so ended up tipping the whole lot onto a tray. Result 3: Although there aren't any full sheets, I probably have enough corrugated to make several small sheds - or at least roofs for a lot of small sheds, and near on the same from scraps of brick. If I was really careful and was happy to freelance a few buildings there is probably at least fifty quid's worth of random plastic here. Light railway anyone?
