* Five different colors of yarn - small amounts. I use Lana Grossa Linea Pura Organico
* Crochet hook as suggested on your yarn label or a little bit smaller. (To achieve a tight gauge with the yarn.) I use 3,5 mm (or 4/E) hook , but 5 mm (8/H) is suggested on my yarn label.
* One pair of safety eyes (6 mm)
* Yarn needle
Finished tractor is about 4.8" (12 cm) long if you use 3,5 mm crochet hook.
