I'm a big fan of Altenew's enamel dots, but the Tranquility collection may be my new favorite. The colors are tranquil, yes, but also very wintery and very marine. With their gray undertones, I've been able to create a whole new mood on my cards--a bit of tempest off a rocky coastline, a sense of fog or overcast skies. Great fun to play with when you live in New England! I love the varying sizes which come in each package, their subtle sheen, and the fact that they always stay where I place them. Another great product!
