First, you'll need to decide what items you want to include in your suite - invitations, envelopes, detail and/or rsvp card, etc. Think about whether or not you want to add design details as well such as wax seals, vellum, twine, ribbon, etc.
Typically I offer three different types of paper: cardstock (white finish with clean straight edges), linen (textured finish with soft eggshell finish), and watercolor/handmade (felt textured finish with rough/uneven edges). However, I am more than willing to source any other kinds of paper for your suite as well.
If any other customization options interests you please let me know!
