Tsumami-Zaiku Fabric: Pure Silk vs. Synthetic, What's the Difference
Search for tsumami-zaiku fabric, and you'll find a lot of it labeled "for tsumami-zaiku." The prices vary. The materials vary even more. It's easy to be unsure what to choose.
So we'll start with the conclusion.
The finished piece is decided almost entirely by the fabric — not the skill. That's what we've come to believe, making kanzashi (traditional Japanese hair ornaments) year after year in our workshop in Nishijin, Kyoto.
What's actually sold as "tsumami-zaiku fabric" today
Most of the fabric currently sold as tsumami-zaiku fabric is rayon or polyester — synthetic fiber. We're not saying that's a bad thing. It's inexpensive, easy to handle, and comes in a wide range of colors. For practice, it's genuinely useful.
But it isn't silk. We think that's worth saying plainly.
What actually differs between pure silk and synthetic fabric
Three things.
- How it holds light — silk fiber has a near-triangular cross-section that scatters light, so instead of a flat shine, it seems to glow softly from within.
- Color — silk absorbs dye deeply. The same color comes out clearer and less muddy on silk than on synthetic fiber.
- How a fold holds — this is the biggest one. Silk remembers the shape your fingers give it. A corner sets crisply and stays. Synthetic fiber tries to spring back.
That third point is something you really have to feel to understand. When we let people handle both fabrics side by side in class, it's what surprises them most.
Habutae — the standard for tsumami-zaiku
Our standard fabric at Oharibako is pure silk habutae: thin, light, with a beautiful translucence.
Thickness is measured in monme (a traditional Japanese unit of silk weight) — the higher the number, the thicker the cloth.
- 6-monme — thin. Delicate, and petals come out light and airy, though it takes a little practice to handle.
- 10-monme — standard. Firm enough to hold a crisp corner easily. This is where we start first-time students.
If you're unsure, start with 10-monme — it's what we teach with first in class.
You can also choose fabric with or without a starch finish. Starched fabric has more body and holds a sharper corner. Unstarched has a matte texture, well suited to the soft, rounded look of maru-tsumami petals.
Another option — hitokoshi chirimen
Alongside habutae, we also carry hitokoshi (one-throw) chirimen from Nagahama, Shiga. This is undyed white fabric, so you can dye it yourself.
There's one thing worth knowing about the name "hitokoshi chirimen," though — it's a little more complicated than it looks. We've written about it separately, for anyone curious.
If you just want to try a little first
You don't have to buy a full bolt to start.
- Pre-cut fabric — cut to size, from 15mm to 40mm. No cutting required, so you can start right away.
- Color swatch set — all 19 colors of our 10-monme habutae. The way silk catches light doesn't come through on a screen; this lets you check it in hand.
- Trial set — 17 colors of fabric plus 10 ochirin (base discs). Enough to get a full sense of it.
