Silk gauze is a 100% pure filament silk canvas. The silk threads are fine but very strong. Silk gauze is woven in a leno structure, which increases the stability of the canvas. Leno weave actually interlocks the weft threads making it almost impossible for them to shift. When to stitch on silk gauze? Stitch on fine counts of silk gauze anytime you want a small, delicate piece of needlework. Miniaturists and doll house enthusiasts enjoy silk gauze needlepoint pieces because you can achieve realistic looking items. For example, doll house rugs, pillows, pictures, and bell pulls can be stitched to scale.
