A clove hitch

• Drill
• Piece of wood

1. In order to drill holes into the compact disks you will need to secure them to something. 
1. Use the bulldog clips to attach each of the compact disks to the drilling board [the wood].
2. Drill a hoe into the compact disk.
3. Thread the twine through the hole in each disk.
1. Do the first, knot it off with a clove hitch,  space it so there is distance between the first and the second.  Do the same for the third, fourth - until there is no more.
4. Hang these up in the garden to frighten the birds away.
