Coptic Stitch Book

I made a Coptic stitch book yesterday, using old collages to cover the board covers and the outside folio on each signature ~ so that the spine would be decorative.  Coptic stitch is a common way to hand bind books, creating horizontal chains of thread that link the signatures together.

The finished book is 5.25 x 4 inches.  The white pages inside are the backs of the collages; the rest of the paper is kraft cardstock.  I used size 8 perle cotton doubled and waxed for the sewing.
