Mailing Lists
Envelopes are most commonly converted from the 'text' weight papers.  Weight is important for many reasons.  Thickness represents a nice quality and durability, but can also add to the weight of your mailing in which you may incur additional postage.  It is important to determine the purpose of your project and potential weight of the complete mailing.  For paper weight info, be sure to see our 'paper weight info' page & chart.
