I had saved a few additional keychains for myself to experiment with marbling using nail polish. Tutorials for this technique have been popping up in my Pinterest feed and I’d used the technique before in a home manicure, but hadn’t gotten around to trying the technique on other materials yet. Leather keychains sounded like a good place to start. I used two colors, black and a pearly sea foam green. Wasn’t sure how the leather would hold up to immersion in the water and polish, so I masked the raw side on a few and left a few unmasked just to see. The nail polish dries quickly, so water damage really wasn’t that big of a concern. The masked leather maintained its soft and pliable qualities, while the unmasked pieces ended up crusty and stiff. Not sure of it’s longevity yet, but for now, it’s looking pretty good. Hoping to try it out on some clutches and wallets next!
There’s a great tutorial on the technique on Brit + Co. Also, I highly recommend wearing rubber gloves if you’d prefer to not have an unexpected manicure.
