So I finally finished my invites (well, almost done...). I need to address the dreaded envelopes, but I'm having a little problem. My envelopes are a coated, metallic paper (StarDream metallic). It's been very challenging finding a pen that doesn't smear. Fine tip sharpies work without smearing, but the black appears to be gray.
Anyone use these envelopes or a metallic envelope who could recommend a good pen/marker/writing utensil?
