Making my own invitations!!

Hi everybody!
I’m getting married in October and I’ve decided to make my own invitations, save the date, thank you cards and name cards. For the save the date we went the cheaper route and bought the paper at Michaels. For the invitations I’m having such a hard time figuring out where to buy “invitation paper” one that doesn’t feel cheap and is sturdy. I don’t know what “weight” of paper should be for invitations. I ordered samples from every website you can think of. But none of them say the weight of the paper! 🤦🏽‍♀️ should I give up on the idea of making my own? And order my invitations and other stationary needs? Please help if anyone has gone through the process of making your own. Where did you find the paper? And do you regret it?
