My favorite sketch book (14 x 10 inches) order

This amazing sketchbook is order made of kraft paper and professionally bound with hardcover and fabric.
It is made in Colombia by my dear friend Mechas who specialize in book binding and restauration of old books.
I love this books because there is something very neutral and non-intimidating about drawing on kraft paper: you can draw with both black and white pencils, paint or whatever you choose and the results are always warm and interesting. It can withstand watercolor, acrylics, collage, you name it !
