Hand print ideas?

GF

I bought some small canvas’s from the dollar store because I wanted to do my boyfriends daughters hand print (shes 8) and our sons hand print (he’s 8 months) over it as a gift for Fathers Day. But I was just wondering if anyone had any more creative ideas besides layering their hand prints. The canvas size is as big as my hand but I can go back and get some bigger ones if I need to. I’m also wondering if anyone has tips about getting my babys hand print to come out well if he is squirmy/makes fists. Thanks!
