She used old book pages and printed images of birds and butterflies on them suing her home printer.
She punched four holes in each page, used hole reinforcers on the backs of each hole and attached the pages with 5 inch strands of crochet thread.
She attached each row of pages to a board at the top of the wall, using tiny eye hooks.
More details can be found on her blog page.

just behind one vignette.
