Here is a pretty simple set that you might use your own animal designs instead of these.

Here are very detailed instructions to make a really nice cloth book.

I made several. the link shows one I made from test stith-outs, which I sewed together on a sewing machine. two 'pages' together along three sides and then a binding to form the spine.
Later I digitized an outline for the embroidered blocks so I could add two pages together in the hoop and in that case I made 2 holes that let me use (key)rings to hold the pages together. and made a two books that way. No picture of those.
To be honest I don't know which method I prefer. Having the tests already it took less time to use a sewing machine. in the case I had to do the embroidery adding them in the hoop was faster.
