Ask me about layaway for items in my shop if this would work for you.
Change your single treadle Traveller, Elizabeth orTraditional wheels to double treadle. Using both feet doubles the energy and encourages the spinner to sit directly in front of the wheel, which is good for the body posture and balance. The cranks are offset 10 degrees so you can start the wheel in either direction without using your hands. The kit includes a new crank, treadle and con-rod joints.
With purchase of either of these kits, you receive an instant $10 shop coupon. For your instant shop coupon, choose wheel accessories, other fiber processing equipment or fiber. I prefer that you make your selections at time of purchase or soon thereafter. This may also save you shipping if they can be shipped together. My fiber shop is here:
