Egg cartons make great shapes for threading!
Look around and see what else you can find. Paperbark bark is soft and doesn’t split. If you needle isn’t sharp enough to go through try making holes with a hole punch first. Leaves work well too. Drill holes in seed pods or gum nuts.
Cut up straws to use as spacers and a burst of colour.
Set the tray up with a threaded needle with a name tag on it so the child can work independently and get used to putting their name on their work.
Some children want to display their work so think of different places and ways they can be hung up.
