The color isn't exactly what I wanted, but it was the cheapest option and hopefully they will look all right when I deliver them to my classroom in 2-3 days after the paint has set.
I originally wanted a black semi-gloss, but this ended up being a gray satin. The paint almost looks like it has a hint of brown or purple in it. Like I said, hopefully they look ok in my classroom.
I designed the shelves and bought the wood. Hubby cut and built the shelves. With paint, wood, etc., the shelves cost about $55.
