Seigaiha (waves); Spica Bond cotton paper

Musubi Labs returns with a paper infused with 25% cotton but weighing just 49 gsm, making it ideal for ink, watercolour and wash alike.

A cotton-infused marvel of modern papermaking

The second paper in our lineup to come from the legendary Mitsubishi Paper Mills in Himeji, Japan, Spica Bond is a marvel of Japanese papermaking.

Traditional art paper can be thick and heavy as a result of its chemical makeup. Mitsubishi's paper engineers set out to break that mould. By infusing fine, high-quality cotton into the paper pulp during the manufacturing process, they managed to create a paper containing 25% cotton — but weighing just 49 gsm.

The result is a paper that, despite being so thin, stands up easily and confidently to watercolour, wash, ink, and pencil — giving your art all the benefits of both a cotton paper and a thin paper without any of the downsides of the latter. Sketches hold fast, washes are imparted an almost ethereal quality, and the page seems to simultaneously accept and express ink and idea.

A pattern across cultures

Originally thought to have come from ancient Persia, the seigaiha pattern entered Japan via the Silk Road in the sixth century. It gained cultural prominence in Japan as one of the key patterns kagura dancers wore during traditional Shinto ceremonies, before later entering use by the wider populace.

Formed of three crescents stacked atop one another, the pattern represents the open sea and its waves, and in Japanese culture is thought to symbolise gratitude for the bounties of the sea and a wish for a peaceful life.
