Based on your description — smooth wooden, mushroom-shaped, with a short handle, found in an old sewing tin — this is likely a vintage tailor’s or sewing tool, rather than a kitchen item. Here’s a breakdown of possibilities:
1️⃣ Needle or Thread Holder (“Wooden Darning Mushroom”)
- Often used for mending socks, gloves, or delicate fabric.
- The rounded top supports fabric while stitching or darning.
- Short handle makes it easy to hold in one hand while sewing.
2️⃣ Thimble or Pincushion Base
- Some antique wooden mushrooms were bases for pincushions, with fabric glued over the top.
- The short handle may have been inserted into a sewing box for storage.
3️⃣ Thread Waxing Tool
- In older sewing kits, small mushroom-shaped tools were used to rub thread over beeswax for easier sewing.
- The smooth top would make it comfortable to hold while waxing the thread.
🔹 How to Identify for Sure
- Check for any tiny holes or indentations on the top — could indicate it held pins or needles.
- Look at vintage sewing catalogs online — these “wooden darning mushrooms” were common in the late 19th and early 20th century.
- Compare size: most are 2–4 inches tall, small enough to sit in a sewing tin.
💡 Conclusion:
This is almost certainly a sewing tool, likely a wooden darning mushroom or thread aid, used to repair or handle fabric. It’s not a pestle or kitchen item, despite the mushroom shape.
