Inspired by the tiny books, I’m re-energized to attack a mini-book that’s been in progress for over a year. Here are the components laid out in an old teak tray I like for beading:
Whisper, 1″ x 1.75″ x 1″ when complete. The tiny fabric pages are layers of linen and commercially printed cotton, hand-inked, and overlaid with ultra-sheer nylon panels. The nylon comes from high-end tea bags, which I’ve been collecting and washing out for a while – because they’re a glassy sheer fabric I haven’t seen anywhere else. (Some people call it hoarding, I call it upcycling.)
The covers are glass blanks I bought at a local bead store, then drilled, etched, and frosted with the aid of a flexible shaft drill. (Yay power tools.) 
I’m looking forward to Coptic-binding it this week.
Added 4-3-2015: Done! I’m very happy with it. More detail, second entry down here.
