Hi to everyone here! I am a new member and am amazed with all the people I have talked with through these forums. I have recenly sent out some sase envies and encountered the same posting problems as other members. My post office people said it has more to do with the thickness of the envelopes than weight. It has to go through their sorting machines, no more humane equation. Anyway I have been working on making no-glue seed envelopes out of parchment paper that are folded like oragami to reduce the bulk of return envelopes. I will post a template shortly for anyone who is interested. Hope this helps all the seed traders/sase. I know how much I appreciate the sase offers, as I have no seed to trade yet. Cheers Goatgirl
