This hat is very quick to make. The picture tutorial for the shell stitch is included.

Materials need:

• crochet hook 4.5 (U.S. 7)
• approx. one skein aran yarn

One size, fits to medium adult women’s head
Height:10’ (25 cm)
Circumfence: 21’ (52 cm)

Abbreviated in U.S. terms.

I recommend it for intermediate crocheters.
