I've always wondered about adding a design to a book that wrapped around the entire cover. I remember seeing some journal cover a while back that had a large Celtic tree that was centered along the spine. I thought that I could do the same thing.
The cross-hatching in the background would require a fine-bladed wood burning tool to keep it from looking too 'mushed' I would think.
To wrap around a journal of dyed pages of mixed colors (green and brown) I thought about making an Autumn-themed book and I wanted to include my new 'spine-animal' design.
