I made a whole stack of handmade paper earlier in the year, and I had this idea in my head to use some to create an open-spine notebook where you could see all the different colours. It's a good feeling when a plan comes to fruition!
Made completely with recycled and waste materials except for the twine. I know it's possible to create twine from nettles so I might have to add that to my learning list.
(I'm a firm believer that life is too short to not learn all the crafts - if that's what you desire!)
I learnt both the papermaking and bookbinding from the book 'The Organic Artist' by Nick Neddo.
