These cards were designed to be in a series. The series themes were nighttime, moonlight, stars and libraries. Together they created a peaceful warm vibe. A feeling you wouldn’t mind giving anyone, Christmas card? Appreciation card? Birthday card? This design works for everything. The purple/blue wash over the cards and the stars throughout help unify the 4 together. If you look closely you’ll notice that they are actually in pairs too. One is the inside of the cabin and the outside. And the other pair is windows and then a farther look right to the fire place.
