When I worked at Y&R we moved to the 9th floor while our 8th floor was being remodeled. After moving back to the 8th floor, they allowed us to scavenge the 9th floor and take furniture that would otherwise be disposed of. I found a giant whiteboard that was a little beat up, along with some other things.
Now that I have purchased my own house it was time for that whiteboard to find it's permanent position in the office. There were a lot of screws taped to the back along with some funny looking fixtures. Everything I've ever hung either used a good old nail or those ridiculously expensive removable sticky tabs.
Enter YouTube. This is where I find the best how-tos so that I can do it right the first time and not waste a lot of time. Here is the video I used to learn how to correctly hang a whiteboard. It's not a great video, but it completely did the trick. I had the fixtures they had in the video and then smaller hooks for the top.
I used a Zircon Stud Finder to find my wood studs because it was too hard to tell the difference in my walls. It was quick and a lot easier than drilling/filling a bunch of holes.
Mark the center of your studs next with a pencil. A white rub eraser will get the pencil off your wall the cleanest.
Ta-Dahh, a beautiful and securely mounted 60 inch whiteboard for all my organizational pleasure.
