Today I'm so excited to introduce my brand new Holographic & Iridescent brushes for Procreate! I've been wanting to make brushes like this for a long time. 

The brushes are particularly well suited to gemstone drawings which is one of my favorite themes, so I've gone ahead and kicked off with a much requested Opal Tutorial. 

I do use some default Procreate brushes for this tutorial as well, so if you don't have the new brushes, you can always follow along and substitute other brushes in different colors as needed.
