I am super excited about how these turned out! My invitations are 5x7, with A7 square-flap envelopes, so I used pre-cut 6x6 cardstock to make DIY envelope liners. So easy and no cutting required!
For the record, I DID NOT take my time on these LOL. An avid crafter or a just more patient person in general would do a much better job. Some of the thicker sheets/designs were way harder to fold than I thought, and then the foil pages show every crease (aka every mistake LOL) - but for something that's going to get promptly thrown in the trash, I think they look great!

CARDSTOCK USED (Purchased at Joanns during a papercrafting sale, $15 for 3 packs. Unfortunately they only had one of the mostly white/gold foil pack left, so I got 2 of the gold packs to supplement it. I could have ordered more of the whiter ones directly from DCWV but I'm trying to be as thrifty as possible and Joann had a much better price. Every person will get a different design but won't know the difference.)

My invites were designed by me in Canva and then printed through StationaryHQ. (Sidebar - I had them printed at Walmart first in an attempt to save some $$, but they were TERRIBLE!! Design was off-center and the cuts were all crooked. I gave them an opportunity to fix them but never heard back so I ended up returning them to my local store and re-ordering from SHQ. I got a great deal because I'm a business owner so they set me up on a wholesale account which includes a built-in discount, and they also had another sale going when I ordered so I was able to double up coupons. $140 in the cart but I ended up paying $80 for 80 invites and envelopes!)
