I knew exactly what I was going to do for this challenge. I decided to use by O.P.I. Spotted that an awesome friend from France got for me. O.P.I. Spotted was released as part of the Spiderman collection in France instead of the normal teal crackle. I think it was also released in other countries, but I can't be sure.
I used a super thin layer of Spotted over 3 coats of FingerPaints Paper Mache. I followed it up with INM Northern Lights Hologram Top Coat in Silver.
You can see some varying effects here. On my index finger, I used a bit thicker coat than on the others. I used the thinnest coats of my middle and ring fingers. I think I like the pinkie the best though.
