I just returned from Florida where I visited my 90 yo mom as well as my son and his family. While there, I was able to get pictures of family "hands". The pictures included one hand of my mom, me, our DIL and our grand daughter - four generations. Then I took one of my DH, my son and our grandson. They will each be framed along with pictures of the people. I had always wanted to do these and finally had the chance to do so. The hands were photographed against a large piece of black fabric from my quilt stash.
I will post these on my website and will let you know when they are posted if you're interested in seeing them. If you have multiple generations and the opportunity to do this, it may be something you'd like to plan.
