Materials
Yarn
Crochet hook, according to the yarn
Scissors
Darning needle

I used a yarn of each 50% mohair and acrylic and 280 m on 100 g. Instead of the recommended hook size of 4.5 I chose a hook of 4.0 since I work quite tightly.

For my dragon’s tail I needed 200 g of yarn.
You can crochet the tail as long as you like or as much yarn as you have.
