A favorite things party invitation

Have you heard of a Favorite Things party? Recently, a customer requested I customize one of my mason jar bridal shower invitations for this type of event. It’s such a sweet idea and a great way to celebrate a birthday or just for a fun girls night! Basically you set a price limit and everyone brings a (specified quantity) of one of their favorite things! And everyone leaves with each other’s favorite things! I think I’d bring either my favorite Amlactin body lotion recommended by my dermatologist (it’s amazing) or for a kitchen theme it would definitely be a kitchen scale — I went years without one but definitely wish it was a purchase I made a long time ago.  It makes baking easier and so much more consistent! What would you bring?
