Anything that clarifies Pipers Silk thread is a bonus. Thank you so much for this Mary. I have known about them for many years and have tried to explain what it is I need, but found inveriably that they have little knowledge about the application of there thread. I have had samples from them on more than one occasion, but the size thread has always been much to fine for the silk gauze I was using, so have gone elsewhere. Generally I like to use a single thread and would go to a larger size rather than doubling the thread.
