This is a break from tradition. Linen thread has long been the thread of choice through the ages and very good it is too when considering the stresses applied to it. However, I think its folly to ignore advances in technology. Tigre thread (Tigre is a brand name) also known as Rizla 25 has been around for a while now, and I think in many ways it is better than linen. It is 100% polyester and therefore almost rot proof. It comes in differing thicknesses/strength appropriate for the product being made and is supplied in a wide range of colours allowing me to offer nearest match or contrast stitching.
