So I just went to the post office to price out the postage and our invites are under weight and normal size for .44 BUT he said since there is a little bump it will be .69. There is a TINY piece of twine around the invite that when tied creates a tiny bump that you have to feel for. I mailed out bridal shower invites for a friend a month ago with a bow that was much bigger and it worked. Should I just go with the .44 or play it safe?
