What kinds of special paper do you have?
For a textured feel, we have linen paper and envelopes in white and natural (ivory).
For a more colorful look, consider using colored paper with a matching envelope.
In addition, we have linen paper with matching envelopes available in both white and natural (ivory) colors. They have a nice, textured feel that's sure to stand out, and are particularly appropriate for end-of-year "asks".
If you'll be including pictures, we recommend the white over the natural, but you can usually get away with either. If you have several pictures, you might consider using our glossy paper or regular ivory paper instead, as the texture can detract from the photos.
For holiday greeting-style letters, we also have a number of designs available. Check back in November to see the designs that will be available this year.
