Based on your description—smooth wooden, mushroom-shaped, short handle, found in a sewing tin—this sounds very much like a darning mushroom (or darning mushroom tool).
What It Is
- A darning mushroom is a traditional sewing tool used to repair holes or worn spots in socks, stockings, or other knitted garments.
- The rounded “cap” of the mushroom goes inside the sock or garment, stretching the fabric slightly so you can weave yarn or thread neatly over the hole.
Why It Looks Like a Mushroom
- The “cap” provides a smooth surface to stretch the fabric.
- The short “stem” (handle) is just long enough to hold comfortably while darning, but it doesn’t need to be long like a pestle.
How It Was Used
- Insert the mushroom under the hole or worn spot.
- Keep the fabric taut over the rounded top.
- Use a needle and thread or yarn to weave over the damaged area.
- Remove the mushroom and check the repair—it leaves a smooth, even finish.
💡 Fun Fact: These were very common before socks became inexpensive, and they’re often found in old sewing kits or tins. Collectors still prize vintage wooden darning mushrooms for their craftsmanship.
If you want, I can make a small visual guide showing different types of vintage darning mushrooms so you can compare yours—it’s surprisingly satisfying to identify these old sewing tools.
