tecedekaxtone | Other versions that I havent tried ....yet....

If you’re working in heavy felted wool you can just make a cut midway on the brim and tie it together and get a brim in 4 parts or cut more as shown below:

Cut the pattern piece E in half and make it in 4 parts instead of 2 to get an overlapping effect
Put an interlining in a contrasting color and make slashes to make it more “landsknechty”. Do make the slashing before you sew all the pieces together!

There’s a rather odd looking variant that has a brim that doesn’t come all the way around: The front part is missing and to keep the brim standing up ties has been attached and tied on top of the head: odd looking but adding ties to drooping brims can be seen in a lot of images so if your fabric doesn’t have the thickness or stiffness, just use ties!
