This beautiful piece has been in my sewing collection since 2019. This came from the English dealer.
The back and front covers are likely cardboard that's covered in a gorgeous purple silk brocade. To add contrast, the creator trimmed in emerald green silk.
The book measures 2.5 by 2 inches. It's 3/4 thick when closed. The front cover has what looks like 2 tiny cream threads peaking through the purple. Inside the front cover is an ivory silk brocade hand stitched with a leaf/ vine design. There are 4 graduated pages, also stitched in green, that are wool.
They have been cut with pinking sheers to prevent fraying. Three of the pages have holes.The last page still has a needle inserted, and the perimeter of the book still has a few straight pins stuck in it. I have displayed this piece in my smoke free home, away from direct sunlight, behind glass.
