I made myself finish the helmetliner last night, and it looks great!
Of course, I had to try it on
I was a bit frustrated when making it, because I ran out of the green yarn too early.
I searched my stash of wool yarn, and found some brown vintage sock yarn in a fingering weight. I held two strands together to make it as thick as the worsted weight I had been using.
I like the way it all worked together. Not bad!
