A chalkboard is a great addition to a homeschool room and with today's dustless chalk and chalkboard markers, it's not messy! Large chalkboards can be expensive to purchase, but making your own chalkboard at home is inexpensive and easy!
I have three ways of making a chalkboard that I would like to share with you. The first one, which is what I did, is to go to our local Lowe's or Home Depot and buy some chalkboard paint. It comes in a whole array of colors, including this spunky purple. I simply measured the space I wanted and penciled it on the wall, rectangled off the area with painters' tape, and painted two coats of the stuff. Then I bought some simple framing and nailed it around the chalkboard with itty bitty nails. The framing comes in 8-10 foot pieces, but if you bring your measurements with you Home Depot (and probably Lowe's) has a table saw with yardstick on the aisle so you can cut the lengths you need right then and there.
Another way to make a chalkboard is to make your own chalkboard paint. It is easy peasy! Just mix 2 tablespoons of unsanded tile grout for every 1 cup of paint. That's it - you now have your own chalkboard paint! The advantage of this, of course, is that you can use any color. So if you want your chalkboard to just blend into a room in your house, or you even want to make a whole wall into a chalkboard but don't want it to be noticeable, you can use the color of your wall.
The third way, which I have just come across and haven't tried, is to buy a piece of sheet metal the size you want and paint it with chalkboard paint - either store-bought or homemade. You can hang it on the wall and either frame it or not, and the great thing is that it doesn't have to be permanent. You can just take it down when you want to. My chalkboard works fine but I am thinking that on sheet metal, the chalk would write super smoothly and be clearer to read. The idea came from Jeanne Winters.
Whichever method you use, paint two coats and allow to dry thoroughly. You'll need to color the entire chalkboard (with the side of a piece of chalk) and then erase it before the first use.
