Cover the silk fiber with another piece of stabilizer and pin through all of the layers to hold the fibers and embellishments in place. Using a walking foot if you have one and cotton thread that matches the silk fiber, stitch through the layers in a 1/2" (1.3 cm) grid, starting with the horizontal and vertical lines in the middle (which will help hold everything in place while you do the rest of the stitching). Stitch the entire piece. It is not necessary to sew the stitching lines perfectly straight.
