Spinning Silk: Varieties, Preparation, and Techniques

Silk is the fiber world's crown jewel—lustrous, strong, and utterly luxurious. But silk is also one of the most diverse fibers available to spinners, with varieties ranging from cloud-soft to crisp and textured. Understanding silk's different forms and how to spin each one opens up a world of creative possibilities.

What Makes Silk Special

Silk is a protein fiber produced by silkworms (primarily Bombyx mori, the domesticated silkworm). Unlike wool, which grows in scales, silk is a smooth, continuous filament that can be thousands of yards long. This smoothness creates silk's characteristic luster and slippery hand.

Silk is incredibly strong—pound for pound, stronger than steel. It's also temperature-regulating, keeping you cool in summer and warm in winter. These properties make silk valuable both on its own and in blends, where even a small percentage adds strength and sheen.

Mulberry Silk: The Classic

Mulberry silk comes from domesticated silkworms fed exclusively on mulberry leaves. This controlled diet produces the finest, whitest, most lustrous silk. Mulberry silk is what most people envision when they think of silk—smooth, shiny, and elegant.

Mulberry silk top (combed and prepared like wool top) is the most common form for spinners. It's slippery and can be challenging for beginners, but it spins into incredibly smooth, strong yarn with beautiful drape and sheen. Use it pure for maximum luster, or blend it with wool for easier spinning and added warmth.

Spin mulberry silk with a light hand and moderate twist. Too much twist creates wiry yarn that loses silk's characteristic drape. The goal is strong, smooth yarn that flows like water.

Tussah Silk: Wild and Textured

Tussah silk (also called wild silk) comes from wild silkworms that feed on oak leaves and other plants. This varied diet produces silk that's coarser, more textured, and naturally tan or golden in color. Tussah has less luster than mulberry silk but more character and grip.

Tussah is easier to spin than mulberry silk because it's less slippery. It creates yarn with a matte finish and subtle texture—perfect for projects where you want silk's strength and temperature regulation without high shine. Tussah also dyes beautifully, taking color in rich, saturated tones.

Spin tussah like you would fine wool—it's forgiving and creates lovely, versatile yarn. It's an excellent introduction to silk for spinners intimidated by mulberry silk's slipperiness.

Silk Hankies (Mawata): Delicate Layers

Silk hankies are made by stretching silk cocoons over frames, creating thin, translucent squares of silk. To spin them, you pull a thin strand from the edge of the hankie and draft it as you spin. The result is incredibly fine, delicate yarn with a soft luster.

Silk hankies are perfect for lace-weight spinning and create yarn with a slightly different character than combed silk top—softer and less lustrous but still strong and beautiful. They're also wonderful for blending—layer hankies with wool or other fibers and pull them together for custom blends.

Spinning silk hankies requires patience and a gentle touch, but the ethereal yarn they produce is worth the effort.

Silk Caps and Bells: Structured Preparation

Silk caps are similar to hankies but formed into cap or bell shapes. They're made from multiple cocoons stretched together, creating a thicker, more substantial preparation than individual hankies. Spin them by pulling fiber from the edge and drafting as you go.

Silk caps create slightly thicker yarn than hankies while maintaining silk's characteristic smoothness and strength. They're easier to handle than hankies and work well for fingering to sport weight yarns.

Silk Noil: The Rustic Option

Silk noil is the short fibers left over from combing silk. It looks like cotton and has a matte, almost chalky appearance with minimal luster. But don't let its humble appearance fool you—silk noil creates beautiful, textured yarn with all of silk's strength and none of its slipperiness.

Noil is the easiest silk to spin, perfect for beginners. It behaves like cotton or a very short-stapled wool, creating yarn with a soft hand and subtle texture. Noil is also affordable compared to other silk preparations, making it accessible for larger projects.

Spin silk noil with short draw, adding enough twist to hold the short fibers together. The resulting yarn is perfect for summer garments, textured accessories, and projects where you want silk's properties without high shine.

Blending Silk

Silk's real magic often emerges in blends. Merino/silk creates soft, strong yarn with subtle luster. Alpaca/silk adds structure to alpaca's drape. Wool/silk combines warmth with sheen. Even 10-20% silk transforms a blend, adding strength and a touch of luxury.

When blending silk, remember that it's denser than wool—a little goes a long way by weight. Blend thoroughly for even distribution, or create intentional pockets of silk for visual interest.

Caring for Silk Yarn

Silk is surprisingly durable but requires gentle care. Hand wash in cool water with pH-neutral soap. Never wring or twist—press water out gently or roll in a towel. Lay flat to dry away from direct heat or sunlight.

Silk can be weakened by prolonged exposure to sunlight and by alkaline substances, so avoid harsh detergents. With proper care, silk yarn and garments last for generations.

Choosing Your Silk

Start with tussah or silk noil if you're new to silk—they're forgiving and create beautiful yarn without the challenges of slippery mulberry silk. Once comfortable, explore mulberry silk top for maximum luster, or silk hankies for delicate, ethereal yarn.

Silk offers something for every spinner—from rustic noil to lustrous mulberry, from easy tussah to challenging hankies. Experiment with different varieties to discover which speaks to your creative vision and spinning style.
