Carrying a wet oil painting home after a painting expedition presents a problem: you don't want to disturb your carefully applied paint or to transfer the said paint onto your hands, clothing or luggage. Commercial solutions exist, but they are generally quite expensive and sometimes quite heavy (I found one example that was made of plywood).
I have discovered that it is quite possible to do it yourself - a carrier made of corrugated cardboard is relatively cheap and easy to make, and should survive several trips into the field. I thought I'd describe how I make them, just in case anyone is curious or in burning need of something similar.
