Hi, I am trying to find envelopes for my invitations in a C5 size in this handmade 'seed paper'. I've seen it being called petal paper, seed paper, flower paper. I can find sheets of it on Etsy but I can't find envelopes anywhere! I was considering making the paper myself as it seems like something I could totally do but I know that will be very time-consuming and I'm worried the cost might be more than if I just bought these envelopes somewhere. However, I can't find envelopes anywhere! I am willing to make my own envelopes if I can find the paper somewhere but I can't find this paper in a big enough size either! If anyone knows where I could find something like this please let me know! I've attached a picture to show what I'm talking about. This picture is from the Instagram of an invitation making company and they, unfortunately, do not sell these envelopes alone.
