I had a several orders for Helmets this past Christmas. Here’s the style I ended up with. The pattern was improvised but based on my version of a Half Double Crochet Beanie. It was created with Red Heart Super Saver worsted weight yarn, and an I crochet hook.
The face mask was an improvised piece combining back loop only half double crochets, alternating black stripes, a loop on each end and a simple crochet “button.”
One of these days, in my spare time… hahaha… I’ll write up the pattern with the face mask, ridge and neck.
