Can the whorl be slid up to be a top whorl spindle or is it affixed in the bottom whorl position?
Thank you for your question and what a great question it is.
Unfortunately no, however, you can purchase the top whorls also.
I have attached two brochures to explain the difference between the two CLASSIC DROP SPINDLE and TOP WHORL
The Top Whorl's can be purchased using the following link Top Whorl which can be purchased as a collection or singular.
