Tufting
Tufting is a type of textile weaving in which a thread is inserted on a primary base.
It is an ancient technique for making warm garments, especially mittens. After the knitting is done, short U-shaped loops of extra yarn are introduced through the fabric from the outside so that their ends point inwards.
Usually, the tuft yarns form a regular array of "dots" on the outside, sometimes in a contrasting color. On the inside, the tuft yarns may be tied for security, although they need not be. The ends of the tuft yarns are then ed, so that they will subsequently felt, creating a dense, insulating layer within the knitted garment.
