Shetland wool has a Bradford count usually in the upper 50's to lower 60's and a fiber diameter range of 20 -25 microns. Fleeces usually weigh between 2 and 4 pounds (1-1 1/2 kg) and have a staple length of 2 to 4.5 inches (50-120mm).
Shetland comes in one of the widest ranges of colors of any breed. Besides the white, the sheep produce several shades of wool including moorit(reddy/brown), shaela (silvery grey), fawn, grey, dark brown and black. They are often patterned such as krunet (white crown), katmoget (dark belly) and gulmoget (light underneath). There are 11 main colors as well as 30 markings, many still bearing their Shetland dialect names. Unfortunately, many of these colors and markings have become quite rare as white wool has historically commanded better prices.
The wool color and high quality is commercially important to the wool industry of the islands where natural wools are often used undyed to make high quality shetland knitwear. Extra fine ring shawls are knitted, so called because the finest can be passed through a wedding ring. In the UK as a whole the wool is prized by handspinners.
