That second gingerbread house has been made - not too much difficulty really. I made the parts yesterday (which is a bit easier than baking a standard batch of bikkies), and got my team onto decorating it today.
So Jessamy, James, Xanthe, Catriona and Connor decorated the house with smarties, freckles and spearmint leaves. Very nice, only just a little messy.
And here's a useful organisational note - the cooked pieces of gingerbread all fit into a Tupperware Slice'n'Store - that's a standard slice container. Very handy to know when you need to put your house parts away overnight.
