Writing with a Quill

I wrote a small note with a quill.
It’s surprising, but this exists, still.
            Yes, I dipped it in ink;
            Quite a mess, you would think,
But that only applies if you spill.

This was in a post office of yore,
Still in use, but with antique décor;
            So they set up a site
            Letting visitors write
With a feather (for sale in the store!).

On the table were dishes of sand
Meant to sprinkle a bit with your hand
            On your writing, to dry it;
            I think you should try it.
The quill should be more in demand.
