This hand-sewn book has wonderful Japanese paper on the covers. It is Katazome paper that I purchased from Hiromi. The red lines form rectangles and squares like windows. Green, black, yellow and red circles are interspersed over the grid. The inside endpaper is also yellow.. The book is sewn in the coptic stitch with red linen thread. This sewing style enables the book to open completely flat. 128 blank Strathmore drawing pages are inside. SIZE is 6.” x 4”
