Some girl hobbies are scrap booking, needlepoint, and latch hooking. Scrap booking I think is the easiest of them, because you are decorating your pictures in fun ways.
One hobby that I've recently taken up is banked-track roller derby. It challenges me physically and mentally and has led me to meet some incredible people.
i know this sounds dorky but, i love to read. Im also going to take up scrap booking soon as well.... Maybe dancing? Singing? ANY sport. Group activities....
