I need an easy way to keep my golf glove stretched so it doesn’t get wrinkled without buying a "Golf Glove Keeper". Is there a "diy" way of doing it?

How often should you replace your golf glove? I’ve heard that you should replace it every 6 practices and every 6 rounds of golf. Is this true?

Also, is there a website that I can buy cheap cabretta leather golf gloves?
