Once I heard that a mat or porch sign that says “welcome” is basically an open invitation for random spirits, bad luck, and whatever else might be wandering by.
So I went looking into what could be the origin of this, perhaps just old superstitions about doors? Here is an exploration on what I found, which was more about the threshold than the mat itself.
Old doorway superstitions
In a lot of older traditions, the doorway was not treated like a random part of the house. It was a liminal space, a crossing point, a place between outside and inside. It was where stranger and family, wandering energy and settled home, could meet.

In some traditions, stepping on the threshold is unlucky. In others, shaking hands across the doorway is thought to bring tension or separation. Even the custom of carrying a bride over the threshold comes from this feeling that the entrance of a home should be crossed carefully.
Another famous example is placing brooms across the doorway, beside the door, or just behind it as a way to guard or symbolically seal the entrance.

So from a folk magic point of view, the front door can act like a “spirit filter”.
Greeting and protection at the doorway
In ancient Rome, people really did place words and images at the entrance of the home. Some acted almost like old world welcome signs, while others were “apotropaic”, meaning they were meant to turn away harm such as envy, bad luck, or the evil eye.

In other words, the doorway could greet and protect at the same time. You see this in threshold mosaics with words of welcome, but also in protective images like Medusa, whose face was often used to ward off danger.
Her face was meant to repel danger rather than invite it, which makes her a strong symbol for doorway protection.
The word HAVE in this Roman mosaic is an old greeting, similar to “welcome” or “greetings,” placed right at the entrance of the house of the Faun in Pompeii
So are welcome mats bad luck?
My personal take is no, not automatically. I think that idea is a newer interpretation built on a much older truth, which is that the entrance of a home matters.
So it depends on how you frame it. To me, there is a huge difference between:
“Welcome, anything at all”
and
“Welcome, blessed guests and good energy only”.
Witch welcome mat ideas
If I wanted a witch welcome mat, I would treat it as part of the protection of the home, not just as decoration. It can be warm, but still intentional.
And if the word welcome feels too open, you can change the wording. Something like Enter in peace, Blessed guests welcome, or Only good may enter gives the threshold a more specific job.
You can bless it, cleanse it with salt, or add a sigil on the underside. You can also place protective symbols nearby, such as a broom, bells, herbs, moon imagery, or an evil eye motif. The point is to make the doorway feel clear about what it allows in.
What do you all think? Do you keep a welcome mat or sign at your door?
With my ADHD I´m always leaning more to the chaos side of witchcraft, too.
I have two outside cape cod hand woven all weather and two indoor plain fleck washable. I have three crystals and home protection spell jar on my windowsill in the entrance hallway. I have another spell jar on a shelf next to the back door. I vacuum my indoor mats everyday and wash them as much as I can as I feel that a dirty mat can trap negative energy.
