Soap
Poppets can be made out of most anything. Wax, clay, soap, roots, corn husks, metal, fruit.
– Madam Josephine
If you can’t sew and don’t have any clay or wax handy, you can grab a bar of soap and carve it into a human figure.
The type of soap might impact the difficulty in carving the soap. If the soap is hard, it might be tough to carve. But if it’s soft, it might crumble to pieces when you cut. Experiment with different types and brands.
If you’re ambitious, you can make your own soap. This way you can incorporate herbs and oils that match your intention for the target as you mix the soap base. Then you can pour the soap into a human shaped mold or pour it in a block and carve it once it solidifies.
