Sentimental gift for FMIL

Hey Guys,

My FH and I got his mother a handkerchief that says mother and a little poem that goes with it, and photo album that says my sons wedding, and we need to get her one more really nice thing that won't break the bank. Any ideas? And, the same goes for my mom, I need to get her something nice to let her know how thankful I am....I just don't know what...any ideas!?
