I know I'm lucky that this snag happened with only four months to go, but...
I picked up the wedding invitations today. It came in a square envelope. Argh! I was specifically trying to avoid the square invites/envelopes because I know they require more postage.
I got caught off guard because FI and I wrote our own invites. Turns out we're wordy and needed longer invites to fit everything we wrote. So we purchased tri folder invitations and got the dreaded square envelopes.
I'll be going to the post office next week to weigh and get the news. Keep your fingers crossed. I had my heart set on the wedding cake stamps.
