need ideas re: gifts for grandparents

caramia582

So, we had DS's christening party at our house on Sunday.  Both sets of grandparents were incredible in helping us with the 60+ person party and we couldn't have done it without them.  I really want to give them some sort of gift that will be a memento from the day, maybe incorporating a picture of Cameron or something.  We are on a limited budget and I was hoping for something kind of unique, not something on one of the bigger photo websites like Shutterfly.

 Anyone have any ideas?  TIA!
