And then, moments after I hung it on the wall, Ruben wrote his first sentence.
I bought a piece of decorative molding that had a ledge big enough for holding chalk and catching dust. I rubbed some mineral oil on it, let it dry, and screwed it directly into the wall studs.
I painted a thin sheet of MDF with chalkboard paint (three coats with a smooth foam roller, and light sanding after each coat with 250 grit sandpaper). I waited three days and then "seasoned" it by rubbing it all over with the side of a piece of chalk and then washing it. I mounted it on the wall with drywall screws and finishing washers.
It has seen a lot of action all week. Julio has become an expert at drawing 7 and 8-pointed stars. What? Your two-year-old can't draw an 8-pointed star?
I'm kidding, of course! He just loves scribbling on everyone else's drawings. And we all love this new chalkboard.
