Cut two lengths of thick wool - one 20cm long and the other 30cm long. Tie a knot at the end of each piece and thread a flat button onto it.

Tie another knot close to each button. Now knot the two lengths of wool together, 12.5cm from the buttons.

Thread both pieces of wool through one of the large round beads. You may need a darning needle to help you do this. Tie a knot close to the large bead and then cut off the shorter end of wool.
