The choice of warp thread should be carefully considered as it forms the foundation of your piece and the structure on which you will weave. The thread should be strong and smooth and able to withstand the friction and stretching created by the weaving action. This cotton thread has been developed by us at a local spinner here in Belgium with the rigours of weaving in mind. It has been hard twisted for strength and durability and the natural smoothness of cotton ensures the weft will move smoothly across the warp.
