This origami folding book has 3 layers of 5 folding pockets. Measures 4.5 inches square.
Chinese Thread Books are an old Chinese Folk Art. Women made these“Chinese Thread Books” to carry their sewing supplies. They would often include threads, snips of fabric, needles, paper patterns and other items all folded and tucked into pockets.
I've made several of these wonderful folding books in the past. Here is a link to my previous posted Chinese Thread Books.
