Oil paintings take time to dry, perhaps three to six months to get them very dry. This means by then they don't get tacky when leaning against each other. In the meantime, they have to be kept separate from touching each other. This means suitable racks.
I have been building up my racks for drying and storing these stretched canvas paintings. The individual items of the racks are bought from Ikea, the furniture chain store. You can see them in the picture below. There are nylon fishing lines stretching tight between the paintings to keep them separate.
