Hi! So I'm in the process of ordering/assembling parts of invitations. My photographer that did our engagement photos made our main invitations. The rest of the inserts I ordered and created myself through VistaPrint to keep it lower cost.... It looks really nice, but since I didn't do this all from a kit, I have only outer envelopes. I had the post office weigh one and I would only need 1 stamp as it is (plus one for the RSVP inside of course) So would it be bad to not have inner envelopes? Or else where could I find nice envelopes? If I don't have inner envelopes do I just list everyone invited on the front of the envelope? Thanks!
