Purchasing a large commercial whiteboard can get expensive, but if you've got a home office or dorm room with a big white or dark solid wall, you can build your own glass whiteboard. Instructables user johnpombrio did just that in his son's dorm room. The result could be a lot more finished, and you need a white or dark background behind the glass to see the writing on it, but at around $65, the price is right. He writes:
Does it work? Yes. Is it the best whiteboard my son has ever used? No. It's the contrast. A white whiteboard with a black marker is, by far, the easiest to see and use. Unless there is a dark background or a white background, the writing is harder to see on a clear whiteboard.
Have you opted to built your own whiteboard instead of buying one? Did you use showerboard, glass, whiteboard paint or another material? Share your secret in the comments.
