Spare Seed’s envelope exchange

Field notes

The service turns a seed giveaway into a self-addressed-mail workflow rather than a conventional swap or marketplace. A giver records the variety and material type, then receives a shareable page; the eventual claimant supplies two stamped envelopes, allowing the return mailing to happen without charging the giver. The form also keeps email private, displays only the giver’s first name, and asks users to stay within their own country and observe local rules.
