I had an experience recently with a lost painting. It had been sold online but I couldn’t find it. I looked for days. In the end I found it in an obvious place and felt really stupid. This would not have happened if I my paintings were stored in a understandable way. So, this has motivated me To get organized.
I am storing my work according to subject matter and size. An interesting aspect of this is the ability to see what I’ve been doing. It’s an education about myself. That’s my recommendation. Go through all your stuff and put it in some kind of order. It reveals what you were really interested in and how you’ve been spending your time.
