Very shoddy tutorial follows...
1. Gather your fabric and clean jars in various sizes (mine once held beans, spices, and artichoke hearts). I simply wrapped the fabric around the jar and cut to size.
2. Make a little face...
3. Cut out little face (I started with an exacto knife and then trimmed with scissors).
4. Wrap fabric around jar and glue at seams (I used epoxy which is still holding up, hot glue or fabric glue would probably be fine too).
5. Add a votive, light, and enjoy the glow :)
