Anyway, I followed my normal routine. I bound the raw edges of the cut off covers with maroon washi tape. The inner liners were damaged, so I added some dark red decorative paper that mirrors the book cloth texture of the covers. The folded signatures were bound to the covers with a single-needle coptic stitch with maroon waxed cotton thread.
I just think it's funny and I imagine someone will like it enough to buy it once it goes up for sale.
