Found these on Facebook this morning posted by Lifelistener.com. There were more but I thought these were interesting enough to share. Well I would never have thought to do this when cooking. And I always pulled it off and throw it away. Headrests can be pulled out and used to break the window if trapped inside your vehicle, I don't have this but it's good to know. That diamond shape is called 'the stud finder' by professionals. These are little black diamonds that you can find at set intervals along the tape. Although these might appear randomly placed, they’re actually in specific positions to help you find the center point between two wall studs. This is going to help me a lot when I hang shelves. When I first started driving and stopped to get gas I would have to get back in my vehicle and turn it around. Now I don't have to do that. Until I find a place to conveniently store lids for my pots this is where they will be. I might teach the baggers a new trick on my next visit to the grocery store maybe some customers too.
