How to Use the Patchwork Silhouette Set As with all Patchwork cutters this is very versatile and can be used in many different ways. The set is primarily designed to cut silhouette shapes from black sugar paste. However it can also be used to emboss directly onto the cake and then infill with paint for a flat finish. If using a firm paste such as modelling paste or flower paste these cutters can also be used to create free standing cake top decorations. For this we would recommend modelling paste which you can make yourself or can buy either as a ready to mix powder or as ready to use paste.
