When my sister asked me to make her a "change of address" card for her new home, I made quite a few prototypes. After she chose the one she liked, I mass-produced that style, but used the other prototypes as cards to send when someone purchased a new home.
Impression Obsession's "New Home" clear stamp set was all I needed. It may be difficult to tell from this photo, but the front of this card is only a window and the phrase. The house is actually on the inside of the card. It was colored with Copics.
