Hi. Did you attach the leather band in some way? Glue, stitch, etc? I ask because I have a nice horse hair hat band I want to use to replace the leather one on my Akubra Banjo Paterson.
Neither. Just friction. The leather band I bought was an adjustable loop. I slipped it over the crown into place and pulled it as tight as I could. Then I slid the leather band off again, made it a little tighter again and then gently forced it back on.
After about 10 minutes of wear it formed to the hat/ my head. I don't think it's going anywhere.
I got the idea from a video tip I saw once. I'll try to find it again and post it here.
