There isn’t a pattern on this post, but if you search Google you’ll find some. This was made by trial and error for my small head.
This project took a lot of time, and was fiddly with the bulk of the cans once they were joined, so I don’t think I would make it again. One and done!
The guys emptied the cans but I don’t think they minded.
I’m going to the St. Patrick’s day parade this year, and I plan to wear my hat!
