This is a very simple way to make a book.....it's called a duct tape binding (if you search on Youtube there are lots of tutorials)....only thing is I had no duct tape and was too impatient to wait to go get some so I used brown parcel tape instead:)
Fasten the front and back covers together with tape....leave a small gap between them
add some colour (paint) around the edges
add the back cover image.......I used paper decorated with ANDY SKINNER stencils
add the front cover piece......this is an old book cover decorated with texture paste through the usual suspects stencil, then painted
add more decorated papers inside the covers and then add pages.....I used watercolour paper from a pad and left the torn edges on
they are VERY simple attached.....folded in half and held in place with a rubber band!!
This means the pages can be easily removed to work on, add more or replace with new ones
