With this 'string and turn'-technique, the beads are being stringed
and the wire is wound together just under the beads.
Place 7 beads in the middle of the wire, bend the wire so that the last
beads come together and wind the ends ½ cm. Place 7 beads on a wire end and
wind a little stem of ½ cm. Both wire ends come together, and wind them ½
cm. Place 7 beads on the other wire end and repeat this sequence as
described before until there are 6 loops.
