1. Collect some colourful leaves or maybe some leaves of different sizes.
Then find a suitable flat spot to lay out the leaves you have collected.
2. Start in the middle then make your spiral going outwards.
You could try different coloured leaves to make a rainbow spiral or make a really big one if you have enough leaves.
3. You can make spirals out of anything you can find. Perhaps try fir cones as we have here or sticks or conkers.
