Disliked making sun hats with a visible seam. Tried several joining methods none of which I found make the seam completely invisible.
Saw the 2 colour spiral, really liked it so decided to design a hat using this method.
Not suitable for beginners
Tricky to start but once you get going it gets easier
4.5 mm crochet hook, DK weight cotton yarn, needle, stitch markers
The yarn I used is Hooked Soft Cotton DK
