I'm kind of in the same boat as you are Antinice. I get to utilize the kitchen table for hobby time.
I bought both my son and I this toolbox from Wal*Mart so we can carry most of our needed project supplies and tools back and forth.
It's big enough that we can put our car model box in the bottom and still have room for supplies (such as sand paper, spools of wire, spray cans, pliers, tape, etc...). The top tray carries, oh I think I have around 30+ paints, brushes, nail files (emery boards), tweezers, pin vise & bits, glues & cements, X-Acto knife and spare blades, toothpicks, etc... Plus there are the 3 compartments on top that 2 are removable. I put some spare left over kit parts in them for customing another kit possibly.
I have 2 old car model boxes on the shelf of my bedroom closet that I store extra paints, glues, brushes, wire, etc... in. But for the most part, the toolbox is ready to go. We took it with us on a week trip to CT one time. My wife wanted to visit her family and then my parents. So I figured as bored as my son and I would be for a week, let's bring the gear. Only thing I did ahead of time was spray the car bodies so they would be dry in time for the trip. Summer time we sit outside at the table with our toolbox next to us. Nothing better, father and son enjoying the great outdoors LOL.
Hope that might inspire some thoughts.
