After watching a YouTube video on making books, I decided to have a try.
basically I used 2 types of card; a thicker and a thinner piece.

I cut about a cm wide length of thick card and about a 12 -13mm length of thin card. I also made some bigger and smaller books by simply increasing and reducing the size of the card cut.
I cut two rectangles of the ticker card and then stuck them together. These were, in turn, glued to the end of the thin card strip. I made sure I had a little border of thin card around the edge.
Once this was dry I folded over the extra length of thin card and glued in place. It was simply a case of cutting off the extra length to match the first bit.
I did try experimenting with a book mark by placing a piece of post it note between the two thicker pieces, but I made it a bit wide and it just looked wrong.
I left it all to dry and then painted the pages in bone white (basically cream) and then the covers in various muted colours.
The open book followed a similar principal but in this case the pieces of thicker card were glued side by side with a small gap in between them.

I cut a piece of post it note to the same width as the thicker card.
I added the extra pages by adding glue to the gap and pushing it in with a cocktail stick. in this case I added a second piece (making sure it was slightly longer to allow for the squishing into the gap)

Basically paint as before.
I used a ultra fine sharpie to add writing by doing little scribbles.
The idea came from:
Gareth has some really good simple ideas (mainly for D&D, but to be honest it can be used for anything mini wise)
Vanessa at the Crafting Muse is another fave…. Well worth checking them out. (The video below is my next piece 🙂 )
