I'm in the planning stages for DS2's birthday cake and hope to adapt one of Debbie Brown's cake designs (spaceship) to make a Meg and Mog cake.
The decorating instructions call for sugar paste for the cake board and some of the cake, but modelling past for the others. I plan on buying pre-coloured sugar paste, but can only see the modelling paste in limited colours (not all the ones I need). The book implies that you make modelling past by adding MC powder to sugar paste. However, it's not totally clear if you can only do this if you're making your own sugar paste and if it's a modification of the process.
So, firstly does it make a real difference using modelling paste rather than sugar paste when making figures? If so, can I just add MC powder to ready made sugar paste or would I have to make/colour my own?
