Any suggestions for free letter writing supplies?

A volunteer emailed Vote Forward to let us know that he has acquired paper and envelopes at no cost through his local Buy Nothing group and on Freecycle. These websites feature goods that are on offer and allow members to post about items they need. Volunteers who need assistance with postage for Vote Forward letters should send an email to stamps@votefwd.org; we may be able to help.  

If you have other tips for acquiring free letter writing supplies that you would like to share with Vote Forward volunteers, please email the Help Desk at help@votefwd.org with the subject line, "Free supplies tip."
