Thank you's

I wrote out all my thank you's for my co-workers who threw me a surprise shower last week. I know not everyone who contributed was able to sign the card so I can't go by that.

Would you give a thank you to everyone or was there and/or signed the card assuming they contributed financially to the shower (food) and/or gift (gift card)?

Or should I just give to those who I KNOW 100% contributed. I just don't want to leave anyone out who did contribute.

Thank you's

All of my coworkers that contributed signed my card, I went off of that for thank you's.

Thank you's

I would give a thank you card to everyone if I knew for a fact that not everyone signed the card. Instead of "thank you so much for my shower" I would write "thank you so much for thinking of me and the little one and helping me prepare". They very possibly did contribute, but at least they showed up and celebrated. It's an easy way to get around the technicality.
