I love the look that nail foiling gives. Super bright metallic finish you can't quite achieve with just polish. I ordered a bunch of nail foil from Amazon and started playing around with it. I tried several times with the adhesive they suggest using, but I found it was just one more step and left everything sticky...and the finish wasn't as smooth as I would like.
I find that it works best with a darker base color polish underneath, but the combinations are endless! Here is a quick tutorial on how I do it, I didn't clean up the sides or anything yet. Hope you enjoy!
