The card is basically a square card as a base with a rectangle added to the top to make it fit into a regular envelope. A very clever idea... and it saves postage that way.
The colors of the card are inspired my art studio. My studio has basically white walls- the only white in the whole house! I am not a fan of white walls (or ceilings) but I wanted lots of brightness and light in there. I painted all of the cabinetry a nice "river rock" beige color and I have been looking for just the right color combo to add to the room to make it pop. It's been a year, and just a couple of weeks ago I settled on green and blue. It's kind of a basil green and a calm medium blue. Now I know what I'm looking for and am more likely to find bargain storage ideas in just the right color!
The good thing about adding color to a neutral room like that is if (or when) I get tired of it, I can easily change it. I'm surprised I didn't go with a deep red that I was leaning toward but the blue and green in some of the designers papers I have really caught me. Maybe one of these days I'll post some pictures of my studio.
