instructions

You'll need to add a little gum tragacanth or CMC powder to your sugarpaste before you begin to model. This will allow your shapes and decorations to dry hard and retain their shape.

Seaweed

1. Take a piece of sugarpaste and roll this into a ball (about the size of a grape). Take the ball and using your hands, roll into a sausage shape. Flatten the sausage into a thin oblong shape using a rolling pin until the sugarpaste is about 2mm thick.

2. Take your flattened sausage and very gently twist several times along the length of the sugarpaste to form a spiral.

3. Using a knife or sharp spatula, cut off the end of your seaweed to give it a flat bottom. This will make it easier to stick to the base of your cake.

4. Create more seaweed shapes of varying lengths and colours.

Barnacle

5. Take a small chunk of sugarpaste and using your hands, roll this into 4 balls of varying sizes.

6. Using the bulbous cone tool, make an indentation in the middle of each ball. Stick the balls next to one another so that when they dry, they will form one solid shape.

Wavy Shell

7. Similar to the seaweed tutorial, you will need to take a piece of sugarpaste approximately the size of a grape and roll this into a ball. You will then need to roll the ball into a sausage shape, before flattening with a rolling pin into a thin oblong, about 2mm thick.

8. This step is a little fiddly. Take your flat oblong in both hands, and using your fingers, fold the sugarpaste horizontally into a wavy shape. Secure at the back by gently moulding the sugarpaste together. Once you are happy with the shape, neaten at the back by cutting off any excess sugarpaste.

Conical Shell

9. Take a piece of sugarpaste approximately the size of a walnut, and roll this out to about 1mm thickness.

10. Next, using a knife or sharp spatula, cut a long, thin triangle shape out of the sugarpaste.

11. Starting at the wider end of the triangle, begin to roll the sugarpaste up to the tip of the triangle. Roll vertically to create a thick conical shell, or alternatively roll the sugarpaste upwards at a slight angle to create a taller shape.

Sea Grass

12. Take a chunk of sugarpaste approximately the size of a walnut. Roll the sugarpaste into a smooth cylinder shape.

13. Take the scissors and cut into one end of the sugarpaste several times.

14. To create more prongs, cut the slits in half.

15. Mould the prongs to make the edges less sharp and bend them different ways for a grassy effect.
