for those of you thinking about cutting some grass in your yard and making a basket: you totally should. just consider that fresh green grass will Shrink as it dries - which is fine, so long as you don't mind your basket being a bit more loose. if you want a tighter weave, let it dry out and then soak it for maybe an hour before using it so it's pliable, but stays at its more permanent volume.
this basket took me... maybe two hours? tops? i forget. it was super easy, except for when the goats and sheep walked by and tried to eat it. see a helpful primer on coiling baskets here.
