By the end of the twentieth century, punch needles often included a depth gauge, so that a pile, on the reverse side of the cloth, of a consistent length can be produced. They also come with a very long needle threader to pass the yarn down the stem of the needle.
There are various forms of needles associated with punch work. The main forms available in 2015 were for Russian burko (burco or berko) embroidery, punch needle embroidery, punch needle rugs and rag rugs.
