The only thing I have handmade at the mo is this ikea Knuff platform thingybob. I was (and still might at some point) going to put it on stilts but she currently nests underneath the overhand at the back, so I might leave it as it is. I made the little ramp on the left out of lolipop sticks and filled in the gaps on the bird ladder with smaller sticks.
I am also thinking of making a hut to go over her sandbath out of lolipop sticks to stop her kicking sand everywhere
