Following the instructions you will be able to crochet a very tiny chameleon 10 mm long.

In order to make such a tiny animal you will need sewing thread and
crochet hook 0.35 mm,
If you don’t have such a micro hook you can use 0.4 mm and 0.5 mm hooks, they are also suitable for sewing thread. The only thing in this case your Chameleon may be little bit bigger than 10 mm,

In order to make eyes and stripes on the body of Chameleon you will need also acrylic paint and a thin brush or a toothpick.

It is better if you know how to crochet, at least you are comfortable with crochet thread and hooks smaller than 1 mm.

Thank you for your interest to micro art.
Best regards,
Lucia
