Baby hand print for fathers day?

My daughter is 10 weeks old and I want to do something special for her daddy for his first fathers day. He made sure my first mother's day was wonderful and I want to do the same for him. We are going to church with our parents in the morning, then spending the rest of the day at home. Possibly going to the park in her stroller if its cool enough. We are kinda tight on money at the moment and so I was planning on making him something. Like a big card with her hand print or foot print on it and writing something special on it. But can I use finger paints on her hands? Maybe a better idea just to do her feet? I am not sure what to do. If you have any ideas they would be much appreciated!
