STD question

I was thinking of only sending STDs ONLY to our out of town family and bridal party- our wedding is on a holiday weekend- Columbus Day.

The thing is there are a couple of people who we are not sure that we want to invite yet- and we can't just not send them an STD- because we have mutual friends and they would see the STD on someone else's fridge.

what do you think?

I would wait to send the STD's until you know who you definetly want to invite

Plus you have plenty of time since you really should send them between 9-12 months before for a holiday weekend wedding
