A while back I picked up a Resistol straw hat in size 7 5/8. I have had a "stretcher" in the hat since I picked it up but I cannot seem to stretch it out to my size, 7 7/8. I am thinking about getting the hat soaking wet and trying to stretch out the hat. Is this going to ruin it? I have some issues I would like to ask about. My hat stretcher is almost at its limit of length at 7 7/8 and is made of wood. I am concerned about getting it wet and breaking the wood. Could I place a wash clothe or something between the strecher and the hat to keep water from swelling the wood? If I had a normal persons size head I would just sell this hat and get one the right size. Getting ANY hat in my size is such a mission that I am looking to kick this hat one size up. Is this a job best left to a profesional blocker or can it be done at home. What is likely to go wrong? Any advice would be appreciated!
