I’m not familiar with Harn. But all I’ve seen of it is of very high quality.
Anyway, a friend of mine is really into Harn. So I printed and bound Harn Pottage volumes 1, 2 and 3 in a single book, covered them in the Free RPG Day 2012 Harn map…
Coptic stitch, sewn headbands…
And an 8 threads braid wrapping around it instead of a latch, splitting in two for ease of closing.
Possibly the flashiest edition of all Harn Pottages. It’s not perfect but I’m really happy with the result.
