It’s a simple thing, but welcome mats can really make a huge difference.
For one thing, they make guests feel more….well, welcome. It’s a homey and inviting touch that is rarely noticed when it’s there, but always missed when it isn’t.
But welcome mats also serve a practical function.
If a mat is present, guests will almost universally wipe their shoes on the mat without even really thinking about it. No mat = no foot wiping. Thus guests will end up tracking a lot more dirt and mud into your home than they would otherwise.
