Hello everyone, I was wondering if anyone has any advice about making a rollable Panama Fedora? I know there’s a particular shape of Planter (with a ridge down the middle of the crown) that is the best for rolling and a Fedora is not ideal but I have seen it done and would like to try. So mainly stiffener recommendations, how much/how little to use so it holds its shape but is flexible enough to roll and be kept in a tube (just for travel, not long term storage)

Thank you :-)
