Jiahe Wanxing's cross stitch says that 1 1CT needs 3 strands of embroidery and 2 strands of hooks. What does that mean?

1 1CT indicates that the embroidered cloth is a medium lattice. Embroider two strands with three strands, and sew the edges according to the marks on the drawings. Just fold it in half with a small thread when wrapping (one is six small strands, just draw 1 strand directly from the middle). In addition to hemming, other embroidery methods are to thread three small embroidery threads into the eye of a needle. Never fold it in half, it will be embroidered into six strands, and the thread is definitely not enough.
