Here I am- totally red butterfly art journal - entirely handmade, with leather-like cover and mixed media papers inside. I am closing with elastic, small leather strap and a charm- Made With Love attached to me. Who wants me? :)
13x 18,5cm (5,11"x 7,28"), 20 pages (40 in total).
As it is a butterfly book, you can take out the pages at any moment, work with them on flat surface, arrange them to your liking and of course- add more pages if you'd like.
The Butterfly art journal with mixed media paper is the yin, to your yang. You've found what you're looking for.
