I tried figuring out how to use some of the more pigmented or unusual colors that I wouldn’t normally wear on my lids, and thought about buying a bottle of Duralin. However, I did an experiment today with my eye primers. As long as it dries completely and “sets,” it creates a perfectly good eyeliner with any angled eyebrow / liner brush. This may not be new information, but I had a revelation last night as I was trying to fall asleep. (Like we do. LOL)
