I bought the little veg. trolley on wheels a while ago and it is great for pulling upto the side of me and putting stuff I need at hand. Like one of the drawers with the colour of paper or card I am using at that time. It leaves more of my desk space free to actually work on. I did get to the point where my only workable space was my glass mat, now I'm determined to keep more space free to work and to keep it TIDY.
These are the two book cases behind me where I heep everything, alot is in plastic boxes and nearly all labelled.
