It is a common misconception, but full Mohair does NOT stretch out over time! Many store-bought cord cinches are blended with wool and other fibers and those CAN stretch up to 6-7”! 100% Mohair (the only thing we will use other than 100% Alpaca!) will “give” a little bit when you cinch it up, but it will always return to the original length we tied it to on our frames.
