How to draw it, step by step

Sweep the floor and wipe it with a damp cloth so the powder grips. Mark the centre with chalk. Then follow the pictures. Each one adds one part.

Make a small filled circle in yellow. This is the centre of the whole design, so place it carefully.
Draw eight short pointed petals around the centre, filled in red. Mark the eight tips with dots first so the petals come out even.
Draw eight short pointed petals in the gaps between the earlier ones, filled in orange. Mark the eight tips with dots first so the petals come out even.
Draw a thin white circle around the design. A string held at the centre, with chalk at the other end, keeps it round.
Add sixteen small green diamonds in a ring.
Draw sixteen short pointed petals around the centre, filled in pink. Mark the sixteen tips with dots first so the petals come out even.
Place sixteen white dots in a ring, one in each gap. Drop a pinch of powder and press lightly for each dot.
Finish the edge with thirty-two small half-circles in purple, touching each other like a lace border.

Tip: Chalk the whole design before any colour goes down, and assign one colour to each person. Work from the centre outward.

Make it your own

Leave out one or two layers to make a quicker version for a smaller space.
Outline every layer in white at the end. It hides uneven edges and makes the colours stand out.
Print the outline, mark who fills which colour, and keep it beside you while you work.
