I saw a bunch on pinterest that came up in those pretty flatlay type photos and started collecting ones I liked onto a pinterest board.
Then I showed them to my fiance and asked them if he liked the overall look. I kind of wanted to find a way to merge all of those invites together into one, but that's really not possible, and I found it quite overwhelming to just pick one. In the end, I designed our invites and all our paper goods in canva, because it gave me more control over the finished pieces.
I got on Etsy and searched for designs and templates that were most like what I thought I was wanting, then designed exactly what I wanted in Canva. I printed them through Catprint and got a great deal by doing that!
I just googled wedding invitations sites. A lot are not cost friendly. I ended up going with trulyengaging by magnetstreet.com. I highly recommend them. I got a lot of compliments on my invitations and they were super affordable and great quality.
I chose based on price. Guests don't care about invitations (besides the information on it), and I wanted to put money towards things that would make their experience better at my wedding. I purchased an invitation suite on Etsy then printed through an online printing company (after reviewing several) called Prints Of Love. I paid $118 total for the invitation suite, 60 5x7 invitations, 60 3.5x5 details cards (with info to RSVP online), 60 envelopes, and gold belly bands. Mine still came out beautiful even on a budget! Best of luck to you!
