I am totally new to quilting but am not new to teens! LOL ;) With teens, especially girls, I would take them to the fabric store with you so they can pick the fabric themselves. Two reasons for this: #1, teen girls can be a tad picky and you want them to really like it after you spend all that time and #2, you can let them see all the cool possibilities so that maybe they can get an appreciation for sewing themselves :) There are just not enough young people sewing these days :(
