This thicker cross stitch thread organiser is crafted from high-strength PP (Polypropylene) plastic. Unlike paper or thin PVC alternatives, the 1.5mm thick PP material ensures durability and resistance to breakage, allowing for long-term and repeated use.Each of the 20 holes has a diameter of 15mm, which is significantly larger than the standard 6mm found in many other embroidery floss organizers. This makes it easier to thread through strands of floss without any hassle. All the holes are machine-polished to ensure they are smooth, preventing any snagging or damage to the threads.This thread storage winding plate is great for various craft projects, including embroidery, cross-stitching, and other needlework. It helps keep your floss tidy and easily accessible, enhancing your overall crafting experience.
