I need some advice. I'm looking at buying a flange so I can reshape my own snap brims a bit more professionally without having to ship it off or leave it with someone. The brims on my hats vary in width from around 2 3/8"-3". I note that there are apparently different styles of flanges such as #810 and #901. What I'm wondering is what style should I be looking for to take care of my '30s and '40s style hats; and can I get away with buying one width (say 2 3/4" or 3") to shape all of my brims, or will I have to get a separate flange for each brim width? Thanks.
