Beautiful bouquets have one bad habit: the petals of their flowers fade, wither and drop off.
But they could last longer if you know the special preservation technique called 'L'ecrin flower'.
Artist Shirley Tsoi Pui-yu shows how you can keep a bouquet of lilac-coloured roses for longer.
What you'll need:
Air-tight, microwave-safe container
Dehydration sand (available from Siheyuan Ornaments: Rm 1303, Workingbond Comm Centre, 162 Prince Edward Road West, Mong Kok)
1 Pour a 1cm-deep layer of dehydration sand into the container
2 Carefully cut off the flower stems if you don't need them for your final design. Sprinkle some dehydration sand between the petals of each flower
3 Place the flowers gently on top of the sand in the box. Cover the flowers completely with more sand
4 Seal the container and let it sit in a shady place at room temperature for three days or until the flowers are completely dry - they will be very fragile when ready
5 Arrange and glue the flowers into your preferred design and frame it.
