Okay... so this is kind of silly, and I know no one will notice but me. I have a color in mind for the cardstock for invitations. The place I'm thinking of getting them from has a color that is a bit more red than I want in the matte, or one that is the color I want but metallic. I know no one will bring the invitation, hold it up next to the centerpiece and say "these don't match... what kind of bride planned this" but it's stuck in my head anyway.
Edit to add: I think the price is the same regardless of metallic or matte.
