Design by Erangi Udeshika from Crochet For You.
This is totally gorgeous! It’s a beautiful mesh that resembles a honeycomb.
I’m not familiar with this stitch, but it looks like it’s a lacy design, which would make it ideal for the cool weather. And if you’re in a cold climate you could simply line it for a super cozy hat.
As for materials, you have the option to use a worsted weight yarn or two strands of a sport yarn. Recommended hooks are a 5mm and a 6mm.
