is it possible as the 'unknow user' to give me an answer on how long/diameter the snuffersock is for the spin.
Is the snufffersock build by yourself?
Sock length is dictated by the location of the snuffer patches. Measure the distance from the upper patch to the head, and from the lower patch to the clew and the tack, the sock needs to be a bit longer than the longest of these dimensions. Diameter is mostly related to the size of the hoop. Although you can build one, it's a bit complex, you'd probably be better off buying one.
