DD has recently painted a plastic garden trough and a large plastic flower pot with a poster paint/PVA mix. I'm enjoying seeing a bit of toddler art out in the garden (though not sure how long before these artistic efforts will last before being destroyed by the weather!)
Any ideas of other toddler-art projects for displaying out in the garden?
We have a wall and give the DSs chalk to scribble on them with, and also do painting outdoors on it. We use a big roll of paper from Ikea and stick up really big long pieces - I like that they can do it much BIGGER than indoors.
You could also get your dd to paint a bird box or a bird table or summat like that (ie buy a plain one from B&Q and paint it).
Mobiles made of collected objects? Shells are good, but you could use pine cones, acorns, anything really - drill holes in them (you obviously, not dd) and then string them in lines tied to a coathangar or a couple of sticks and hang up where teh wind can catch them.
