Crushed walnut shells

Using walnut shells in pin cushions has several advantages:

1. Weight: Walnut shells are heavy, which helps keep the pin cushion stable on your work surface.

2. Needle Sharpening: The abrasive texture of the shells helps keep pins and needles sharp.

3. Compaction: They compact well, providing a solid fill that retains its shape.

4. Allergen-Free: Unlike some other fillings, walnut shells are free from allergens like dust or chemicals
