Deckle edge

A deckle edge is the rough, slightly feathered border that runs along the natural edges of handmade or mould-made paper. Unlike a machine-trimmed straight edge, a deckle edge tapers gradually, with stray fibres protruding in a soft, uneven line. It’s the visual signature of paper that hasn’t been cropped down from a larger industrial sheet.

The name comes from the “deckle” — the wooden frame that holds the pulp during papermaking. As the pulp drains, fibres collect against the inside of the frame and form the paper’s natural border. When the sheet dries, that border carries the impression of the frame: uneven, fibrous, slightly thicker than the rest of the sheet.

For most of paper-making history every sheet had four deckle edges. Modern mass-produced paper is made as a continuous roll and cut down to size, which removes the deckles entirely. Mould-made fine-art papers fall in between — produced on a cylinder mould that mimics the hand process and retains a deckle on two or four edges of each sheet.

Whether to include the deckle edge in the framed presentation is an aesthetic choice. Some collectors prefer the print float-framed within the mount so the deckle is visible — usually with a deep mount and a small air gap around the artwork. Others prefer a crisp window-cut mount that hides the deckle entirely and shows only the image.

A deckle edge isn’t a guarantee of quality on its own — cheap paper can be sold with a faux deckle — but combined with archival fibre, proper weight, and a real watermark, it’s a useful sign that the print is made on fine-art paper rather than mass-market sheet.
