Weddingbee boards

So I'm working on my Engagement Party Invitations and I REALLY need help with the wording.  I thought, who better to help than all of the wonderful bees?!

Here are the details:

FI and I are throwing the party for ourselves- if you've read any of my past posts, you know of all the negativity surrounding my engagement and we wanted something positive.

We are having the party at a park near my parents' home- we rented the pavillion and the baseball field next to it.  We wanted to engage the families in a friendly game of baseball (his family are from Philly and are Phils fans, my family is from NY and are Yankees fans), the idea was to reenact the Yanks' sweet World Series Victory

Family and the bridal party members will be invited

I will be doing the cooking

It's mostly informal, but I still want it to be nice

I am using the 5 1/4 x 7 3/4 invitation on the link below
