Our extra strong thread is perfect for heavy-duty projects like upholstery, thick fabrics, and bold topstitching on denim. This small but mighty collection gives your stitches the strength and durability they need.
For beginners and home machines, we recommend using this thread only in the top spool. For the bobbin, pair it with a matching Sew All Polyester in the same colour for smooth, trouble-free sewing.
