Hi ! I would think making paper gingerbread man or peace doves would be simple .
Theres a few ideas here on hometalk https://www.hometalk.com/search/posts?filter=paper%20christmas%20ornaments
Buy some clear glass christmas balls make sure the tops come off, pour few drops of 2 or 3 colours of acrycilic craft paint into them swirl the paint around then turn them upside down and let the paint continue dripping down I found red, white and a gold or blue and silver are the nicest but you can use any combination you like. I used medium sized disposable coffee cups to rest the upside down baubles on to allow the excess paint to drain. Put the caps back on and tie a piece of colourful ribbon to hang them on the tree. I made some but unfortunately I don't have a photo because I don't have the baubles anymore we downsized and we gave a lot of stuff to the kids. Enjoy
