After my cutout map experiments, I've been thinking about the idea of making one-of-a-kind handmade cards with map imagery. One way that's been successful so far is three-layered handcut map cards. The cards are each a piece of thin paper folded in four; blocks are carved out of the top layer, and houses are carved out of the second layer. When the card is closed, the writing layer provides the background. I suppose that if you were to write densely enough on the card, the writing would show through in the houses.
I'll be showing a few of these cards at SLAM the weekend after next, and if that goes well there should be more available at Somerville Open Studios! They are also currently available on Etsy, if you're not in the area.
