My BMs and my FMIL just hosted my surprise bridal shower (and two other people helped them out a lot). Am I supposed to give them a gift more than just a heartfelt thank you card? I sort of thought that the gifts you give them later covered the work they put into the bridal shower. I know that those extra two people aren't in the WP, but I thought that if it was okay, a thank you card to each of them would be okay.
Any input is greatly appreciated!
