...please. The set-up - Night: 85 degrees. High humidity. Dinner, drinks, dancing, drinks ( repeat, save for the dinner part ). Sweating. Wearing 1950's Stetson Open Road. Home after two am. Tossed the hat on the table. My favorite vintage hat shrank a full size, at least!!! The plan - Kiwi leather lotion around the inside of the sweatband, then on the jack over night. Tight, but not to strech yet. Re-apply Kiwi, then on the jack to stretch, over a light steam. The hat jack over light steam worked well for stretching my Federation IV, as they tend to run maybe a quarter to half a size small. However, my OR has gone down a full step, for sure. I look like a pinhead ( more than usual ). Anyone want to throw something in on this? Suggestions? Leave it to a professional? Thanks.
