DIY Chalk Boards
For this project you'll need your board (I found mine super cheap at Goodwill but I hear they are also affordable at Hobby Lobby), a sponge paintbrush, a sponge paint roller, paint - acrylic and wall paint both work, non-sanded tile grout.
Mix 2 oz. or 1/4 cup paint with 1 1/2 tsp non-sanded grout. Stir it up until it's almost smooth (it will remain a little gritty). It will stink a little, kinda like a perm so do it outside if you can or in a well ventilated areal.
Glob it on your board - or just paint it. Pouring it this way is just a little faster, but potentially more messy too.
Smooth your paint out evenly, but leave it a little thick on the board.
Gently roll the sponge roller over the board in one direction until the paint is smooth.
(Learn from my fail: If your board has edges like these paint them first)
Optional step: I painted a boarder on top that included my kids names and made them unique from the others.
Last staple a ribbon to the back. A staple gun would be your best option, but if you don't have one (like I don't) a regular stapler will do the trick. Just be sure to hold it steady and use lots of pressure straight down.
