Large Cotton

The Large Cotton is the thread used to sew weft hair extensions onto a braided track during a sew-in application. It is durable enough to hold a weft securely throughout the wear period while remaining gentle enough not to cause damage or tension to the natural hair underneath. It is the recommended pairing with the Hair Choice C-shaped Extension Needle.

Choose the colour that most closely matches the base colour of the weft being sewn in. The thread sits between the weft and the braid track, so matching it to the weft keeps it hidden if any thread becomes visible at the edges. Cotton is available in blonde, brown, and black to cover the most common weft tones.

Yes. The Large Cotton works with any standard hair weft regardless of hair type or brand, including the Hair Choice Signature Flat Weft and Tape Hair Extensions cut into tracks. It is compatible with both machine weft and hand-tied weft constructions.

Thread usage depends on the number of rows, the width of each weft, and your sewing technique. As a guide, most full head sew-in applications use between two and four lengths of thread across all rows. If you are doing regular sew-in appointments professionally, buying in multiples ensures you are never caught short mid-application.

Yes. The Hair Choice C-shaped Extension Needle is designed specifically for working this type of thread through braided tracks and underneath weft pieces. A standard sewing needle is not suited to this application and makes the process significantly more difficult. The needle and cotton together are the complete pairing for weft sew-in application.
