Once I had put away everything I could find a home for, there was nothing for it but to turn the selection of shelf pieces in to actual shelves in the cupboard that used to be above the calorifier (hot water tank). We've never made good use of this space, but it was also ineffective as an airing cupboard - the lagging on the tank was too good. The first shelf took a while, but once I got going the rest were much quicker.
