This is a link to my current front door mat, can’t say it keeps everyone away but it certainly gives them a good idea of the welcome they’ll receive…

I’ve also got a sign on my door asking people to not to knock my door and use my Ring Door Bell instead – which is much easier to ignore rather a couple of big Police knocks
