Make one large flower of each colour (yellow, pink, blue/teal). Roll out the flower paste (gum paste) to about 1 mm. Let it dry from both sides for a short while (the paste needs to hold the shape but can’t be very dry). 

Use a carnation cutter to cut out a flower (I used a 2.5 cm cutter). Place the flowers on a foam pad. Thin the tips of the petals with the round side of the dresden tool (radially outwards - see the arrows). 

Fold the flower in half as shown in the photo (if the paste is floppy, leave it to dry for a moment before folding). Roll it (see the curved arrow). The centre of the flower should be rolled quite tightly. If the base of the flower doesn’t stick together you can apply a small amount of glue before rolling.
