The parametric thread holder is a practical and functional solution for anyone working with yarn in their sewing projects. It is designed to allow you to keep your thread neat and tidy, so it doesn't clutter the surroundings. The clever design consists of two parts: a plate that easily connects to your sewing machine, and a separate yarn holder that ensures your yarn is always easily accessible. Whether you use it for small or large projects, this holder can help improve your sewing experience by making it easier to work with yarn. Its compatibility with Singer sewing machines makes it an ideal choice for both hobbyists and professionals.
