Silk Education Series #1 — Is Your Silk Actually Silk? Here's How to Tell 🔍🧶
Share
🧶 You've invested in beautiful silk yarn. You've done the burn test (Part 1 — it passed!). Now comes the question nobody warns you about: where on earth do you put it? Silk is not wool. It does not forgive neglect. But treat it right, and it will reward you with decades of lustrous, gorgeous crafting. Here's everything you need to know.
🤔 Why Silk Needs Special Storage
Silk is a protein fibre — just like your hair. And just like your hair, it responds to its environment. Too much light fades it. Too much moisture encourages mildew. Too little moisture makes it brittle. Moths love it. Dust dulls it. The good news? None of this is hard to prevent once you know what you're doing.
☀️ Rule #1 — Keep It Away From Direct Light
Silk is photosensitive. UV light — from sunlight and even strong artificial lighting — breaks down the protein structure of silk fibres over time, causing yellowing, fading, and weakening. This is especially important for undyed or light-coloured silks.
Store silk in a drawer, box, or opaque bag away from windows. If you display your yarn stash, keep silk away from the sunny shelf.
Leaving silk skeins on an open shelf in a sunny craft room. Your beautiful Magenta will become a sad, faded pink within months.
💧 Rule #2 — Control Moisture (But Don't Dry It Out)
Silk likes moderate humidity — roughly 45–65% relative humidity, which is typical of most European homes. Too damp and you risk mildew; too dry and the fibres become brittle and prone to breakage.
Store in a cool, dry room
Add a silica gel packet for long-term storage
Ensure silk is fully dry before storing
Airtight plastic bags (silk can't breathe!)
Damp basements or hot attics
Storing silk while still damp
🦋 Rule #3 — Protect Against Moths (Yes, Really)
Moths love protein fibres. Wool gets all the bad press, but silk is equally at risk. The larvae of the common clothes moth (Tineola bisselliella) will happily munch through your precious silk stash if given the opportunity. Don't let them win.
🌿 Cedar wood blocks or balls
💜 Dried lavender sachets
🌺 Rosemary or cloves
🧴 Breathable cotton or linen bags
Mothballs (toxic, smell terrible)
Plastic sealed bags (no airflow)
Storing near food or strong scents
Cardboard boxes (attract moisture)
📦 Rule #4 — The Right Container Matters
| Container Type | Verdict | Why |
|---|---|---|
| 🧴 Breathable cotton/linen bag | ✅ Best choice | Allows airflow, protects from dust & light |
| 📦 Acid-free tissue paper wrap | ✅ Excellent | Prevents colour transfer, archival quality |
| 🗄️ Wooden box with lid | ✅ Good | Dark, breathable, add cedar for moths |
| 📦 Cardboard box | ⚠️ Short-term only | Can attract moisture; line with tissue paper |
| Sealed plastic bag/container | ⛔ Avoid | No airflow; traps moisture; silk can't breathe |
🌡️ Rule #5 — Temperature Matters Too
Silk is happiest at room temperature — 15–22°C. Think of it like a European summer holiday — pleasant, not extreme.
Cool bedroom drawer
Wardrobe shelf
Dedicated yarn cabinet
Hot attic in summer
Damp basement
Next to radiators or heating vents
🔄 Long-Term Storage Tips
- Re-skein loosely — don't store silk wound tightly; it can distort the fibres
- Label everything — fibre content, weight, yardage, and purchase date
- Check every 3–6 months — inspect for any signs of moths, moisture, or yellowing
- Air it out occasionally — a few hours in a cool, shaded room does wonders
Breathable. Dark. Cool. Dry. Cedar nearby. That's it. Follow these five words and your silk will outlast your other yarns by decades. (And probably your houseplants too.)
