Tiger Thread - the Best for sewing leather:
Tiger thread, also know as Ritza 25, is highly regarded as one of the finest threads available for hand stiching.
It's an extremely strong, waxed polyester thread that is somewhat flat and provides a superior appearance as it lays better in your sewing groove.
Manufactured by the Julius Koch Co., Germany and in 0.8, 1.0 and 1.4mm widths, and several colors, and available only in 500 meter spools from the manufacturer.
We stock the 1mm thread as we've found that for most applications you don't really need the 0.8mm widths. We can provide lengths of 25 yards and 50 yards in the popular colors shown above.
We do carry the 1.4mm thread for your heavy duty projects, but currently only in white. We sell these through Etsy at www.etsy.com/shop/leatherwurx
If you require 500 meter spools Contact us and we can price them for you.
