Chalkboard Creation from Goodwill frame

I got this frame from Goodwill for about $5.  It holds a 14x18, very odd. 

It was wood

And very dingy but I loved the profiles

So some black paint, sandpaper, a coat of poly...

Then a custom cut 14x18 painted with chalkboard paint...

My oldest doing his coloring.  I want the chalkboard to say something like
"Rhyne Diner"   "CowTown Cafe"  I don't know.  I can't decide, so for now it sits plain.

But I definitely need some chalkboard pens.

Maybe I'll just keep it blank so I can always change it.
