There's this huge crop called Happy Scrappers Jam that takes place every Spring and Fall. They offer classes, food, a chance to shop.
This fall's Happy Scrappers jam is going to be on September 18.
This takes place on Oahu. I'm not a sponsor or anything just a fan. I would go if I was still living in Hawaii. There is a cost I don't know how much it is this time around.
