Materials (I used):
Nylon String 50g (7 WPI), 3.25 mm crochet hook.
Nest = 7.5 inch long (Without tail)
About the pattern:
Start with working round. After crocheting few rounds, used rows to make a hole from 7 to 11. If you do not like to crochet in back loop and front loop, you can crochet it in the normal way too.
