These are special three prong round metal tacks which are said by many experienced silk painters to be the best for holding silk onto a wood frame. But be careful, if wet they can stain the silk. They are made of steel and nickel plated. These are actually useful for stretching any kind of thinner fabric, not just silk. Great for stretching cottons for Batik and hand painting, just generally useful to have around!
