Sunflower House. Fun to play in once the sunflowers grow tall. Cute!!
A garden rock caterpillar. a fun spring project for kids (or me...)
Make bird feeders from oranges
Bean House- this would be amazing for the kids!
20 plants that can handle foot traffic (for pathways and varied surfaces in a outdoor classroom/playscape)
Make your own nature stones. Rainy day activity! Collect leaves, nuts, seed heads; press into home-made salt-dough and bake in oven. Paint or varnish.
Never mind the children, I love this!
Seasonal Gnome: Garden Loom. This is beautiful for summer grasses and flowers, but you could leave it up year-round and weave in autumn leaves or winter twigs with berries!
