A novelty item that was used many years ago! Remember when Grandma crocheted over bottle caps and created as hot pad or trivet? This is easy knit! You will need about 13 metal bottle caps or small drink bottle caps, so start collecting or ask your friends to help you save these. Uses worsted weight yarns, and knitting needles US # 5. This is a very unique gift to give someone for a gift! Finished size is about 6 long.
