Lofts are a godsend... Not just for books
I really ought to 'board' our loft. But I get terribly claustrophobic up there, even though I installed a proper light a few years back and a little ladder.
I already have a motley collection of old doors - rescued from skips etc - laid across the joists as a form of rough flooring, which helps to spread the load. It also reduces the chance of me slipping between the joists and falling through, again! Once was enough, when I was about fourteen, and there is a smooth non-artexed patch on my bedroomed ceiling to serve as a reminder.
As well as the books there are model boats, model planes, cycle parts, some motorcycle parts, weapons from the arena days, and odds and end of furniture which was too good to throw away, such as a carefuly dismantled cabin bed which was also pressed into service as temporary floor boards.
When I needed an oversized rectangular cakeboard for a specialist wedding cake I went into the loft, came back down with a cupboard door drom the cabin bed, temporarily removed the handle and hinges, and then covered it with extra wide kitchen foil secured underneath with duct tape. A layer of icing complated it before carefully positioning the cake on top and getting on with the rest of the decoration. For a smaller cake a bit of cheap whitefaced hardboard would have been ample, but for a really big and heavy cake I needed the structural strength. If the board bends the icing cracks. Half inch chipboard is pretty tough stuff.
I'd be lost without my loft ;-)
