For those of you who make cut-and-sew hats (i.e. newsboys, flat caps, etc.), what do you use for the brim?
I've previously used two-ply buckram or heavy-weight buckram combined with interfacing. I've gotten decent results, but I'm so picky, I want it to be perfect.
I know that pre-bought brims are also available. Plus there are thermoplastics. I haven't used any of those options for brims yet.
What gives the best result? What looks the most professional, do you think?
