I wanted to offer keyrings at a couple of Christmas Markets I’m doing this year and came up with this amigurumi single crochet version with a cute little star. The beads and heart charm are optional.

I’ve used double knitting yarn for this on a 2.5mm hook but you could make it in whatever yarn you wanted. It is US terminology throughout.

Size
2.5 inches (6.5cm) long by 2 inches (5cm) wide
