A.M.
I would say make it a potluck so you don't have to worry about feeding everyone (most ladies know how stressful and expensive cooking for a large number of people can be). Just have everyone bring an appetizer like dish so you have munchies to pick on in between chatting. A cheap way to do the wine tasting would also be to have everyoneone bring their favorite bottle of wine or one that starts with the first letter of their name. A great thing to keep things organized would be to use the evite website. It is free (no postage for invites) and people can update their RSVP easily. You can also have them sign up for what they are bringing in their RSVP so you avoid too many chips and salsas! Hope you a have a great night.
