I'm going to pop a post about this in Arts & Crafts too.
I have a couple of empty white plastic garden troughs. They are a good size and would be perfect for what I need, just they look a bit stark and ugly against the wall.
Rather than chucking them out and splashing out on something different, I'm thinking of getting creative and painting patterns etc on them.
Has anyone done this before? If so, what kind of paint works and will a) stay on plastic and b) be fairly weatherproof & suitable for outside?
Thanks
