Waxed polyester filament splits into individual strands for fine beadwork or combines into thick cord for heavy-duty leather stitching. This versatility makes artificial sinew valuable beyond leathercraft, it adapts to whatever your project demands. The wax coating provides just enough grip to prevent slipping through awl holes while maintaining smooth pull-through during saddle stitching. Unlike natural sinew, this synthetic alternative won't dry out, shrink, or degrade over time, ensuring your stitched seams stay tight years after completion.

Thread it through needles for beading projects where you need strength without bulk, or use full-thickness strands for lacing leather sheaths and securing buckles. The 20-yard spools contain enough material for multiple small projects or one substantial piece, whether you're constructing a leather belt, weaving a dreamcatcher, or stitching decorative patterns into bags. Three color options let you match or contrast with your leather and beadwork. Leatherworkers appreciate how cleanly it pierces prepared holes; beaders value the control when working intricate patterns.
