[header] How to make a chalkboard [title] Choose a picture frame based on your desired chalkboard size. [step] You can repurpose an old frame, pick something up at a second-hand shop, or buy something new for this project. The size of the frame will be the finished size of your chalkboard. 
[substeps] When selecting a frame, choose one that still has its backing. The backing isn't necessary, but it will help you secure the chalkboard later.
