This little min-journal is a really simple book. I used the cut-off ends of the signatures of a book I made a few days ago-so the pages were already cut and folded into sigs. I cut a length of the lambswool leather the width of the book and 2 1/2 times the length, folded it in half and stitched in the signatures using a long stitch binding with brown linen thread.
I left the fore edge long and ragged for an organic look. I slit holes in the two long flaps and threaded a soft leather thong through them, then tied the ends of the thong in a loose knot. To open the book, you untie it, pull the covers apart and let the thong loop back over the book. That way, you don't have to keep threading and unthreading one end of the thong through the cover slit.
This would be nice to stick in a pocket. You could just put your hand in there every once in awhile and feel it's cozy softness. You could also hang it form a belt or purse, but someone might ask about the tiny dead animal you were carrying around.
