The pattern is written in US crochet terms.

We will crochet in continuous rounds and will not join the rounds in the end.

For this pattern, I used sport-weight yarn but you can also use DK-weight yarn. Another suitable yarn for this project will be a lightweight yarn. Just make sure to use a suitable crochet hook. To have a more sturdy crochet key cover you can use a size or two smaller than the suggested on the yarn label.

I did not tie my chain on top but you can do that to prevent the chain from slipping. You can place a wooden ball as well.

Materials you”ll need

  • sport weight yarn- I used Yarn art jeans
  • crochet hook size 3mm
  • key ring
  • tapestry needle


SC- single crochet

SS- slip stitch

CH- chain

Rep- repeat

Inc- increase (make 2 SC in the same stitch)

MR- magic ring

– repeat the stitches in the ** indicated times

FO- fasten off
