I am considering DIY-ing my wedding invitations and response cards as I haven't found anything resonably priced that I absolutely loved. I know that there are a TON of variables to the price, but I would love to know the price you all paid for your set of invitations with envelopes and response cards. I priced one set I did like at about $600 for 150 invites, response cards, and envelopes. Is that average or expensive? Thanks!
