These needles are especially designed to finish your hand woven products. The needles are longer than normal needles and have a small round knob at the tip. The knob is there to prevent the needle from piercing a thread when fixing or correcting your work. This way the needle picks up the thread instead of going through it and the thread can easily be woven back into its correct place.
The needles come in three sizes, 5.5 cm, 6 cm and 9 cm.
The shorter needles are for fine work, while the 9 cm needles is more for rougher hand woven articles.
The picture only shows two sizes (6 + 9 cm)
