Silk Habotai

Silk Habotai, also sold as China silk, is a fine, smooth plain weave and one of the most basic silk constructions. It is light and soft with a gentle luster, less shiny than charmeuse but with a clean, even surface that drapes fluidly. At roughly 40 to 70 g/m² (about 8 to 12 momme) it spans from a featherweight lining grade near 8 momme to a firmer scarf and blouse weight around 12 momme. The lighter weights are near-translucent; the heavier ones hold enough body for a soft-tailored lining.

Its most common job is lining. Habotai slips easily over other layers, adds no bulk, and breathes better than synthetic linings, which makes it standard inside jackets, skirts, and dresses. Hemmed scarves, lightweight lingerie, and silk-painting blanks are the other main uses, since the smooth undyed surface takes dye and paint cleanly. It frays along cut edges and the fine yarns shift, so handle it gently. Hand wash cool and press warm on the reverse; a hot iron on the face can leave shine marks, and water can spot the lighter weights.

For sewing, use a fine 60/8 or 70/10 sharp or microtex needle and fine thread, and shorten the stitch to stop the slippery weave from puckering. The cloth slides badly, so cut on a single layer over a matte surface, weight the pattern rather than pinning across the body of the fabric, and pin only inside allowances. French seams or narrow rolled hems control fraying and finish the interior of a lining or scarf cleanly. A walking foot or tissue paper under the seam helps feed the light cloth evenly through the machine.
