September is a big month for me, and in a week I have to make 2 birthday cakes (a police car and a dragon) and a christening cake.

I want to have a go at fondant and a 3D cakes as there is nowhere around here (in the country) that does them.

SO
Can anyone PM reasonably priced online cake decorating supply stores?

How close to the occasion does the cake have to be assembled (I have 2 functions on the one day)?

How do I store them?
