I had a restoration project that I enjoyed doing today. This original half Jullian easel (made in France 🇫🇷) needed a little TLC with some metal polish, WD-40, Butcher's wax and leather conditioner. The first thing I did was polish up the metal components. Then I used Butcher's bowling alley wax because the wood was dry. Some of the wood also needed a fine grit sanding. The last thing I did was apply something called "sno seal" to the leather handle. You could also use Leather CPR or another product to condition the leather.
These photos don't do justice to this beautiful easel. I think if I hadn't become a painter then I would have liked to have been a furniture maker or woodworker. I've always enjoyed working in wood shops, maybe in my next life..
