My 4 year is suddenly motivated to tie knots. He is trying to tie knots on everything. So I made this contraption from things around the house. Took me around 3 minutes to make this.
Egg carton (any cardboard box will do)
Brightly colored shoe lace (any thick rope will do)
something to poke holes
Sticking agent ( I used cellophane tape)
Step 1: Make and Done
Take the egg carton and poke 2 holes in it.
Tie a knot in the middle of the shoe lace.
Pass the shoe lace through the 2 holes in the carton.
Close the carton and seal it with a cellophane tape.
You are done.
Give it to your kid and help him/her to tie the perfect knot.
You won't require much time and he will take over fast.
