This is a small reindeer keychain pattern.
I made it using a 3mm crochet hook and dk weight / light worsted weight cotton yarn, with this yarn & hook, the keychain is 5-6 cm tall and 4 cm wide.
Gauge is not important for this pattern, just make sure the hook and yarn fit together, so the reindeer does not have holes.

You can use some leftover yarn, because this pattern is small.

I recommend making this as a keychain (then you need a keyring, mine was 2.5 cm in diameter), but you can also attach it with some yarn
