These type of simple ideas, that let kids run wild with their imaginations, are the best!!
A leftover piece of cardboard (delivery box, cereal or pizza box, any kind!), some glue and off they go!!
A lovely idea for kids to potter and do at home, in a local park with friends, or you could go for a forest walk to gather bits and make another day.
It can be created loads of times and the best thing .. it’s different every time and completely child led!
