Hand appliquers and quilters everywhere often question me about which threads I use for hand applique. My prefered choice is the YLI silk thread. They are 100% pure filament silk, the very highest quality silk thread in the world.
As many of you know I prefer to work with natural fibers throughout my quilt. This includes fabrics for the top and backing, batting and threads for piecing, applique and quilting. I carry the 100wt. silk thread in my quilt shop in a great variety of colors. When I open my silk thread collection to select a color its like opening a box of candy. The colors are so vibrant and rich. Remember to use only one strand of thread when selecting one to match the applique piece. You match the piece and not the background color. Lie one strand across the fabric to be appliqued and it should be nearly invisible.
Use this thread with a straw needle to make nearly invisible needle-turn applique stitches. In my hand applique booklet, I explain the stitch, step-by-step.The straw needle I prefer to use is very thin, with quite a small eye, but since the 100wt silk is so fine its really easy to thread the needle. The long length of the straw needle gives me leverage as I turn the needle under the applique and provides complete control of where the point of the needle will exit.
