Hubs work Baby shower appreciation

So my husband comes home and tells me that his office is going to throw him a little shower in October and the admins want to know where I am registered.. I was so touched that people who don’t even know me want to do this for my husband and impartially loved it cause there was no mention of me going and I’m glad he gets to feel celebrated.

He comes home today to tell me that I am invited and they said I should add stuff to my registry cause and email is going to go out and there could be a lot of people buying.. again I am so touched. It I want to do something for the office, I was thinking making scones or treats to bring in to them randomly before the shower so they can Atleast see me before I come in and say thanks for the gifts.

Any thoughts of what I should make or anything else I can do to show my gratitude??
