A recent post by Marianne Post (who is primarily a pastel painter) asked “where do oil painters store wet paintings?” This is a serious question because oil paintings can take anywhere from 24 hours to a few weeks to dry to the touch, depending on what medium the artist uses. (This is where acrylic painters and watercolorists laugh. They, of course, don’t have this problem.)
A trick I learned a couple of years ago from another student in an art class is this: an inexpensive dish drying rack. It works perfectly as a painting drying rack, at least for smallish paintings on panels of boards. Here’s one that I use:

I have another, slightly larger one, too, that I use for boards up to about 12 in by 16 in.
Small stretched canvases can fit sideways, if you don’t have too many boards in the rack. For larger canvases or panels, about the only solution I’ve found is a shelf. Lots of oil painters have narrow shelves molding on their walls just for this purpose.
What do you use for storing wet oil paintings?
