long hair no ideas on styling

I have long auburn hair that is pretty straight, it has body but not a whole lot of curls. my hair is down to the middle of my back. i always wash it brush it and that is it, i mean i do get compliments on my hair but i need a style, or better yet ideas on how to do different things i am open to try anything, i just don't want to cut my hair too short. i am going on a few trips this summer and would like to have a few different styles to do. i'm pretty desperate...thanksheather leannDieselgl@aol.com
