It was driving me mad the big gaps of wood on my little shelving unit. I know that sounds strange but it needed to be filled with something. I suddenly thought till I can afford one of those vintage letterpress drawers I will need to label my rock specimens some how. So I decided to use some scraps I had of an old map which had one of those fabricated backs, perfect for typing on and so wrote out my labels. So now the gaps have been filled and I am now very happy, even though it all looks a bit messy and mad, but that's just me.
