I found a super simple tutorial for DIY lip tar by The Makeup Box

I did a couple things differently just to make it even simpler for me; namely I stored the lip tar in a little round container with a snap-on lid (I have a bunch lying around.  They came with a bead kit) and I stirred it in the container with a toothpick.

The tint is blue eyeshadow from a palette that’s too intense for me to be comfortable using on my eyes.
