This is a great tip from Yvonne Reilly. How to set up your easle over a door. This is a great space saver if you have limited studio space. You may be able to adjust this idea to also hold wet paintings and get them off the floor!
This is just a simple rectangle with a couple of pieces of aluminium bent to hold it at the top then bent to go over the top of the wardrobe door. A couple of plastic doorstops screwed to the back saves it from hitting on the doors. This setup takes medium size canvases up to very large works which can be as long as the entire wardrobe.
