Pack slips (More menu, or Mail day) are signed-in cut-and-tuck cards. Each slip has who the envelope is for, city and country, their skip list, and a line for what you packed — never a street. Tuck it under the note. When you get home, copy that line onto I mailed it so they see it on Open mail. Packing notes on the swap thread stay private to you.
A typical pack-slip sitting
- Print pack slips. Cut on the dashed line.
- Write what you actually packed. Skip their do-not-send list. Default is scent-free.
- Tuck the slip in the envelope. No street, tracking number, or password.
- At home, copy the same line onto I mailed it (optional, they can see it).
A pack slip is not a mailing label. Don’t show up at a penpal’s house. Don’t put a street on paper you might photograph.
