I have many stamps but no letters, what am I?

In spaces we dwell, I bring charm and flair, a touch of style here, a splash of color there. I'm the quiet artist in your room's attire.

I was a moment you lived, now a ghost in your head, Born from a scent or a word someone said. I pull you backward through a door in your mind, Leaving the present and the future behind.

I’m a whisper of scent, Carried on the breeze’s soft touch, Loved, but unseen.

Kids might play on this in a playground Adults might do this to spice up their marriage
