Thanks for all your ideas! The scrapbook idea is very creative and would be sentimental to them...my parents would love that just for the mere fact that I made it! My parents tell me all the time that the best presents in the world are my sister and me.

In fact, we're driving home from school this weekend to surprise my mom, and even dad, for Mother's Day! The look on my parents' face will be of sheer shock because they have no clue we're coming home this weekend.
