Not my work

I've had a new tapestry for a cushion - will blip it soon. This one isn't my work, far too intricate.
Our neighbours have a problem with sewage backing up in their drains and flooding the garden. Apparently it comes from an external drain so not their responsibility to fix. Unfortunately the Water Authority will not be able to tackle it until Saturday so we are being ultra cautious about how much we are putting into the drains.
