Made of a polyester core wrapped with cotton, this leather and saddle work thread is also called polycotton. It is presented here on small 900 metre cones. The size, 28/2, is expressed in metric numbering, hence the mention NM. Read all about thread numbering in Madame Sajou's Diary. The 28/2 represents a thread with a thickness size 28 twisted in 2 strands or ply. The finished diameter is 0.38mm. Available in four thicknesses: 28/2, 28/3, 28/4 and 50/3. ATTENTION: these threads are available on order. Delivery times can vary according colours and quantities.
