I don't think we'll do one cuz neither of us speak in hashtag lol or have a Twitter or Instagram. But I was playing around with the generator one day and it gave me #PrangPartyof2 which I liked a lot!
We cannot in any manner seem to find an appropriate for us wedding hashtag due to FH's last name being Gay: #gaywedding #gaymilitarywedding and so forth aren't what we are wanting to convey.
