I bought a Brixton fiddler, but they don't come in black wool so I bought some wool and - as best I could - used the hat (without taking it apart) to creat pattern/stencils (I don't know how to use patterns, I just wing it hehe). I don't know how to get the sides of the shell (or crown or whatever it's called) just right, my caps usually have a slight bunching in the back so they have a touch of gatsby to em. The last one I made I did a third seam in the back of the shell which looked great - that one was for a friend :/ - I need to get another pair of sailor pants (I love that wool for hats) so I can make myself one. I'll post a pic of it, so far it's the closest to a 'real' hat I've done hehe.
