Drive two nails into a table or board, the distance between nails equaling intended string length. Determine the number of strands needed: breaking strength of one strand, divided into four times the bow draw weight. Wind the string back and forth around the nails until desired strand number is reached. Be careful to apply equal tension on each strand.
Tie the two loose ends together.
Slide the string around the nails a few inches so the knot can be covered by serving
Serve for about three inches. (Use medium-fine soft cotton, silk or linen for serving.) Serve similarly at other end.
Slide the string back to its original position. Form loops by pulling the strings together and serving.
Serve about three or four inches in the centre of the bow for the arrow nock.
