I took eight 4-sheet signatures of Ingres paper in various shades of blue and earth, and stitched 'em up in a coptic stitch...
with handmade hemp endpaper from the papermaking class I took last spring... (the hemp fiber was a bit overbeaten, so the wrinkles pictured are natural to the paper)
and a splash of handmade kozo (mulberry) paper, also from papermaking class...
with a cover made of soft recycled leather wrapped around boards.
And the best part is, I did it all with a friend. Bookbinding is better with company. Her coptic book is more than twice as big, has a gorgeous cloth cover, and will make a great sketchbook.
