So traditionally all the envelopes would be address with caligraphy both inside and out. Ours are folders with belly bands so no writing on the inside. Would it make a difference to you the reciever if the envelope was hand written/caligraphy or just a label/from a computer? We aren't planning on sending out invites till January so i have plenty of time to address 100 invites but what are your thoughts? The rest of the invitation is completely handmade and printed by us if that makes any difference.
