These books are beautifully made- they are stitch bound with a fabric spine. The cover is left as blank book board so you can either draw your own cover or use your own book cloth or paper to create your own cover design. The books measure 8-1/8 x 11-3/4 inches. Each one has 144 acid free pages. The interior paper is natural eggshell color and has a vellum surface- just enough texture for pencil and pastel. Paper is 100g (approximately 60lb weight). The stitch binding allows you to open the book flip pages and lay the book flat without having the binding crack. Available with four different color fabric spines- yellow red black or blue. Sold individually- the photo shows the colors available but pricing is for one book only!
