I bought some forms for "sand castles" (or what they are called in english) in my latest holidays. 1€ each...
Today I spend 2 hours slapping a little paint on one of them...
Added a few walls to make the whole structure a little bit bigger and to be able to game in the inside...
I ll keep the roof removeable.
Put some filler on the form and the walls.
And with some paint on it. I think I should add a second colour for more contrast. Like blue walls or roofs...
Cheers,
