Using the pencil and ruler, draw three 6cm x 10cm rectangles on white paper.

Cut out the drawn rectangles along the edges.

Next, mark points every 1cm along the 6cm edge of the cut rectangles, then fold the 10cm edges inward along these guide points.

Secure the folded paper strips with tape.

Roll up the paper strip and overlap the ends by 1cm, securing with tape.

Take out the yarn and cut it into 15cm lengths. You'll need 24 pieces in total.

Fold each yarn piece in half, and as shown, pinch the ends with your right hand, thread the yarn through the ring from the inside, pull through and knot. Patiently repeat this process until the ring is full of yarn.

Choose a different coloured yarn and cut a 20cm length. Fold it in half and tie a knot at the end.

Thread the knotted yarn piece through the yarn-covered ring and pinch the remaining yarn to adjust the knot length.

Then take another piece of yarn in the same colour as the hat, and tie it at the top of the hat as shown to secure everything. Make sure to pull the string tight so the yarn doesn't unravel.

Finally, use scissors to trim the excess yarn at the hat's top, aiming for a round pom-pom shape.
