Follow the instructions to tie the knots
Knotting sheet printed & either laminated or stuck to card - one for each cub - string, selotape & hole punch
Make up the boards (cubs can do this if glueing to card), punch holes at the bottom with a hole punch & thread string through from the back so that you've got 2 ends to tie the knots with. Selotape along the back to hold the string in place. Practise knot tying - can be followed with a knot relay.
