For my pinky, I used Mrcandiipants style multi-line design. You can find the tutorial Here! I used a lot of colors and overlapped quite a bit, which left it with the softer look.
On the ring finger is a feather, over an "acid-wash" wood. I originally was going for a brown gradient, but somehow this came out. I layered three browns, light to dark, and then used a striping brush dipped in acetone to strip the layers back. This ended up as a really cool effect!!
The middle finger is what inspired this whole set! I saw a tutorial for turquoise with a golden saran wrap effect. Sadly, it wasn't by the original poster and lacked a watermark, so I can't give credit here. I did differ from the tutorial - I did two layers of saran wrap effect. The base coat is a dark turquoise, followed by a light turquoise saran wrapped, then a gold glitter saran wrapped.
This wasn't the exact effect I wanted, but I think playing around with the layering will pull off what I want ^^
Finally, the thumb was inspired by the all the dreamcatcher nails I've been seeing on tumblr! I wanted to add my own spin, so instead of painting it from the base of the nail to the tip I went sideways. When I was little I really loved dreamcatchers and find the folklore behind them fascinating.
