From old bathtub to wormery. The bricks and bits of old paving are holding down a fine mesh screen in a vain attempt to keep the rats out. The plug hole is blocked up with a piece of paving and a large pebble beneath it leaving no gaps.
This replaces my last large wormery made from a garden storage chest left by the previous owners. It gave a couple of years of use but fell apart. Hopefully this will be a bit more sturdy!
