To get this plaid-ish, wrapped-present-ish look, paint a layer of black, and then a layer of your multichrome (because multichromes can be kind of thin, and these bottles are pretty small so I wanted to make sure I didn't waste time on a lot of layers). Let everything dry (I waited probably 20 minutes), then add your striping tape in a plaid pattern.
You really do have to be careful with the tape, as I ended up peeling a big chunk of polish off of my ring finger when I pulled it off! I was able to fill it in with a polish brush, but it wasn't quite as neatly done as a tape manicure should be.
I'm really honored to be able to participate in Artsy Wednesday, and you should all DEFINITELY check out these other, very talented Artsy Wednesday participants.
