I seem to be addicted to making stuff, I apologise!
Ok, so hears an idea for a house. It was very fiddly, as you need to press the mache down firmly, but it's impossible as you also have to be gentle. I have no idea how this will dry out as it's the first I have tried. But it was fun, so here goes......
The loo roll tubes got soggy so I removed them. I just turned the whole thing upside down and added some mache to the joins. seems to have helped. It's in the oven now to dry out a bit, lowest gas mark.
