I really like this mixed hearts design from Pueen. I'm not usually a fan of heart-themed items, except when it comes to my nails it seems. I've ordered many a stamping plate solely because of a cool hearts design that I saw and decided I had to have.
To stamp the hearts pattern, I used Robin's Egg Blue from Rica on Etsy. I had pulled out both Robin's Egg Blue and the blue pastel Konad Special Polish as possible stamping colors. Robin's Egg Blue was just a touch more pale than the Konad and I thought it paired with the KBShimmer polish better.
I do love a good monochrome manicure. I don't know if I just prefer the way they look, or if it's because I kinda suck as mix-n-matching colors when stamping! Maybe a little of both.
