Like SugarMillCakes, I have a craftsman tool box. They are on caster and you can stack them. In fact this year my tool box became larger than my grease monkey boyfriends! I love my tool box. That thing holds EVERYTHING!!!! I even have my rarely used pans in one of the drawers.
When I am working on a cake, I can roll it out into my work area so that i have easy access to it and then just roll it back into the pantry out of the way. Best investment I have ever made, and got it for a great deal thanks to fathers day!
