There are multiple uses for Teeswater Locks. The staple length of these are averaging 5 1/2 inches. I've washed and lightly processed these by hand and are sold by the ounce. If you plan on spinning with these remember that Teeswater Sheep have a 40-60 Micron count and would be best spun worsted or used into an art yarn. Sold in 1 ounce packets.
