Activity for Alison

I plan to order flip flops for my female wedding guests for when their feet start to hurt. I have some questions for those of you who have done this before or who've already done the research: 1. How many pairs should I order? I'm expecting about 90...

Anyone have any luck getting their invitations hand cancelled in NYC? I've heard it depends on the particular post office but haven't ever gotten advice on which locations are good ones to try. Please let me know if there are any NYC USPS branches...

I received my invitations today and think they look quite plain so I'm considering getting envelope liners. For those of you who used them, how long did it take you to assemble them in the envelopes (and how many envelopes)? Thanks!
