Raamtekens (or WindowSigns) are curtains or room dividers that come in cut-up loops that can be intertwined to the width and length of your choice. Because they are made from cast-off advertising canvases or mesh, no two Raamtekens are the same with all their different colors and patterns. The effect in the end is a mostly transparent curtain that obstructs visibility looking in, but still leaves open visibility looking out.

Designed by product designer Esther Derkx in the Netherlands, known for her collage-like ceramics, and most likely available through her site, though not currently in the online shop.
