Using the CK LaceMakers :

Use a 50/50 mixture (50% of each) of Sugarpaste (Rolled Fondant) and Flowerpaste (Gumpaste), though you may need to adjust the proportions depending upon the pastes being used. Experiment to find what works best for you. The mould should be clean and dry and dusted with cornflour (cornstarch), though if you use lustre colour, the lace pieces will have a pearlised finish when they come out of the mould! (NB. You may find that paste tends to stick in a new silicone mould, so you should use it a few times to "get it working")

STEP 1 : Dust both sides (both pieces where they will come into contact with the paste) of the lace mould with cornflour. Roll the paste out thinly and trim to a suitable size to fit over the mould. By rolling the paste thin, the finished lace will look more delicate.

STEP 2 : Lay the paste over the mould and with a finger, press onto the design, so that you can see the outline clearly.

STEP 3 : Carefully place the other piece of the mould over the paste to fit the design and then press firmly to make sure that you get a good impression.

STEP 4 : Holding the top part of the mould in place, tear away the excess paste.

STEP 5 : Remove the top piece of the mould and with a rounded palette knife blade carefully neaten the edges.

STEP 6 : (optional) Where there should be holes in the lace design, carefully remove some pieces of paste - this will give a much lighter and more realistic effect, but it is not necessary to remove all the pieces.

STEP 7 : Turn the mould over and by lifting at one side and curling the mould, the paste lace should fall out onto the work surface.

STEP 8 : Attach the lace pieces to the cake before they are dry to get them to curve smoothly over rounded edges. Alternatively, dry the pieces on a flat or shaped surface and then position on the cake.
