There are many fine papers on the market for letterheads. Most of the time letterhead is printed on a water marked sheet such as Classic Crest, Classic Linen, Classic Laid, Beckett Cambric, etc.. These papers are generally 24# weight and contain cotton. They have matching envelopes.
Occasionally, churches choose to have a heavier paper than the standard 24# weight. The next weight up in the fine paper lines is called "text". Text weight papers are usually 70# papers. They are not watermarked and do not generally contain cotton. The text weights usually have matching envelopes also.
We recommend using a quality paper and unique design.
