The pattern calls for Dupioni silk for the background fabric. Too expensive for me so I used a dark cocoa brown sateen (similar to lining fabric). The thread is Coats & Clark metallic gold. It took 8 spools of thread. And I used all white pre-wound bobbins. Not even one white dot of bobbin thread pulled through the dark fabric. Finished quilt is 70" x 60". Lots of blocks in the design and borders. The most difficult task was piecing and sewing the squares so they lined up evenly to make the picture.
