Build up the base gradually so that the segments take on a regular shape. Then tie on the QBA with consistent tension and controlled overlaps. On a small hook, limit the thickness of the thread under the quill to maintain a slender abdomen. Stop wrapping before reaching the thorax and secure the end with a few well-placed wraps. The QBA is supplied in lengths of approximately 1 m; this is different from the natural QBN quills sold individually.
