Considering that towels are textured, I also used textured polish. Light blue is L'Oreal - Distressed turquoise, while dark blue is OPI - Wharf! Wharf! Wharf! Because you can't stamp with textured polish, I used Jessica Phenom - Blue blooded. images are from BCS005 plate from Aliexpress.com.
I've done my nails last night, to be ready at the crack of dawn for day in the sun, but unfortunately, there was none of daylight left for me to take pic. I dread winter months and light box pictures that give you this 'natural' tan like on this one...
