Gift for stepmom

I love my stepmom to death and I really want to get a nice, sentimental gift for FH and I to give her at the rehearsal dinner..anyone in the same boat and/or have any suggestions??
TIA

maybe something sentimental could be a really nice crystal picture frame with a picture of you,FH, and stepmom. Thats what i gave FMIL for mothers day last year and she loved it

ETA: Sorry thought you said FMIL not stepmom i changed it to stepmom =)
