The question is asking for “swade”, but I think the correct term that should be used is suede. If suede is the correct word, the optimum suede length for sheep is generally around 50 millimeters or around 5 centimeters. This answer is just right if we are to compare the answer given by “Svyns1”, the creator of the AHW1: Sheep & Goats questionnaires. To make a suede, a sheep’s fur or wool is normally needed.
The wool, once sheared from a sheep, can be made into different type of sheep skins such as: 1) The traditional long wool sheep skins which are used to produce pillows, rugs, car seat covers and winter hats, 2) Curly Wool sheep skins which can also be used for rugs and 3) Medical sheep skins which are soft and resilient wools that are used for bedding, elbow pads, seat pads and heels.
