Hello all

I'm hoping the seasoned bakers amongst you will be able to help me please  

I am currently making two Christmas cakes and really need to decorate them before 1st December as I am taking a late holiday and won't have time to finish before Xmas when I get back.  My primary concern is that the coloured fondant icing may bleed into one another, I intend to store them in cardboard boxes under my stairs to keep them cool.

I am using my own MMF, some of which will be coloured using sugarflair paste and also using red and black renshaws fondant icing.  I will be glueing using homemade tylose glue.  As an example I will be making santa, twisted coloured ropes that sort of thing.

I've never decorated cakes that far in advance and would hate to come home to a multi coloured mess!

AI doubt you will have problems with colours bleeding to be honest. My main concern would be that the MMF would be really hard by the time you go to cut it a few weeks later.
