I've never been so happy with Shellac layering before. I got the idea from I Heart Cosmetics blog to layer Gotcha & Strawberry Smoothie. What did I get? Barbie pink!
Here's what I did:
Shellac base coat - cure for 10 seconds
1 coat of Gotcha - cure for 2 minutes
1 coat of Strawberry Smoothie - cure for 2 minutes
Shellac top coat - cure for 2 minutes
This looks a lot like Zoya's Barbie shade. It may be very Spring/Summer, but will sport it for 2 weeks in the Fall nonetheless.
