The details are that I used the grey twill sashiko stitch-out, cotton batting as the filler, a cord I made several years ago from leftover embroidery threads and a big, old grey button. The button has peices of 'Crystalette' (pink in reality, white in the photo) on it as an experiment in how this product works. I found it in a sale bin in Canada but it is distributed by Kandi Corp. in Clearwater, Florida. The website can be accessed here. The trim is some old dupioni from a failed project. I left the edges raw, which may have been a mistake as it seems to shed more every time I pick up the book.
This project worked and I think I will add it to my repetoire of things to make with leftovers ... besides zipper pouches and little dog toys.
Have a great weekend!
