So to review: tie the end around the nostepinne's notch, wrap perpendicular to the shaft to start, then continue wrapping at an angle until you reach the far end, untie and slide off. Important tip don't pull tight, or you can get big clumps of yarn 'barf' when working from the center. Style tip if you always wrap over your existing work you can get the 'cake of yarn' shape.
The nostepinne shown is hand turned from cherry. I make them out of a variety of woods and shape the handles for comfort. The yarn pictured is some of my handspun. A two ply, 194 yards, from 4 oz. of superfine alpaca hand dyed by Flying Goat Farm. I spun and plied all of it using top whorl drop spindles from my personal collection.
