Postal letterboxing for beginners

I'm new to postal letterboxing myself, so I thought this would be a good swap to help us all dip our toes in the water (but I will be arranging a chain/round robin swap later, if you would rather have more partners). In this swap we will each only have one partner, which will give us the opportunity to create our own postal letterbox - which can potentially be used again in future swaps.

For this swap, you will create a postal letterbox.
Your postal letterbox could be a re-purposed (large) matchbox, or a playing card box, or any other kind of box that all of the following will fit inside of:

• a logbook (at least 8 pages, size to suit your box)
• a hand-carved rubber stamp (this can be carved from an eraser or lino)

In addition, you will need:

• a hand-carved signature stamp (to stamp the log book of the letterbox that you receive, before returning to sender)
• a personal journal (this is kept by you, & only seen by you. This is where you will record any postal letterbox stamps that you receive. It can be any format you like.)

Optional:

• you can include a small ink pad in your postal letterbox, but I think it is safe to assume that the recipient will have their own
• the stamp included in your letterbox can be mounted or unmounted - it will probably not last so long unmounted & be a bit fiddlier to use, but mounting could add considerably to the weight of your package

I will be adding some resources/links in the group forum about letterboxing in general, about carving your log/signature stamp, & also about basic bookbinding, but feel free to add comments/questions below!

How it works
When your partner is assigned, you will send them your postal letterbox. They will rate you based on the letterbox they receive, and - after stamping the logbook with their signature stamp, & taking an imprint of the letterbox stamp in their personal journal, they will return your letterbox to you. (There is no way to rate the return of your letterbox, unless you & your partner set up a private swap.)

When you sign up to this swap, although you will only be assigned 1 partner, you will mail to 2 people:
* You will mail your own letterbox to your partner and
* You will return the letterbox you receive to the sender (after stamping its logbook etc).
