Bias-cut silk is a great fabric to make trims with. Silk in a flat, tight weave works best. Silk taffeta is probably the easiest to use for trim. Silk organza works well. Silk satin works well, too. A spongy or unstable weave like silk crepe or charmeuse will be a little harder to work with. Don’t attempt to make trims with stretch silk. Here are some photos of trims that I’ve made in the past:
