After searching for 1 1/2 years for a replacement thread that was as good as my favored Fufu, I have finally found a thread that is equivalent to it. It's superiority above other machine embroidery threads will be apparent with your first use. If you love the strength and durabiltiy of polyester and the sheen of rayon, then you too will love these threads as I do.
*PLEASE NOTE: Poly X-40 has rebranded their name and is now called Exsquisite. You may receive a combination of the thread labeling but the threads are the exact same.
