Still learning the trade

Can you guess they're small~?

OK, ok, so before I can do biiig things [like finally binding the 2.5 kg A4 size Liber Chaotica Complete] I'm experimenting on small sized books. Here I tried to craft a quasi-codex [the red 'un] and a spring-back mini Chaotica.
First try was 2 years ago btw: meliadhor.deviantart.com/art/c…

Both o' those little things are filled with hand dyed and cut pages, sewn together; circa180 [red] and 140 [black] pages. There are no endbands on the red one as the early middle ages books didn't had those. Black book has a pair of white cotton endbands. Clasps on the red book are made of metal, and I sculpted the dragonheads from polymer.
