I found some items that can help you create what you are talking about. I focused not only on art, but also on sculpture, knitting and handcrafts. I hope it helped you :)
(they are available on market, but it's rare to find)
artist's brush (paint)artist's brush artist's canvas artist's palette Easel (or easel kit) Artist's Easel & Masterpiece of Gozzler of Muse & Painting of Muse of Gozzler
to create it you need items in advance: artist's brush with paint (use palette on brush) + canvas + easel kit. You can also buy it from players.
in my opinion, these items can be useful as tools for creating sculptures, as paints, as containers-tools for artistic accessories, as paints, sewing supplies
I would say following items are perfect for your decoration:
