I am on a month and 11 days from when I married. I just have to pick up my picture thank yous which are ready and then just put the stamp on them. 2 months TOPS for me!
My husband had to leave 3 weeks after the honeymoon, so guess who had to finish all the thank you notes. Boo...But, I managed to get the 120+ thank you''s out in less than 2 months. Maybe not great, but I was happy with it.
We sent out the very last few about two weeks ago. That put us at just under 3 months after the wedding, and I had hoped to have them all out before then, but at least the majority of them were about a month after the wedding.
