As it happens, S., I'm actually in the process of making another batch of "Walkabouts: travels and conclusions in verse" (second edition - with simple letter-notation tunes included) paperbacks now. For what it's worth, the most difficult shoe-string task is trying to print my "shoe" onto 220/240 gram A4 card - for the cover. I shall then replace the one in my bag, the one in my lounge room (read annually), and, of course, donate one to the good RIV Library! (as I've done to about 50 other libraries). Otherwise, it's all free on the web as a kind of e-book and an e-scroll.
