Tips for working with mixed media
Mixed media is fun and easy to implement together if you enjoy being experimental. When first starting out it is good to have an understanding of what mediums can work together. I always keep an art journal with trials and tests, with notes, so that I can refer back to. Water based and oil based products are a good one to be mindful of, you can place oil based products on top of water based mediums but not the opposite way around.
It is fun also to mix up the surface on which you work, as medium alway behaves differently depending on the surface that you choose. It is all about enjoying the process and I don't believe there are any rules to it other than that, so paint on what you want.
