I don't know about your kids, but mine bring home countless art projects from school. I have to pick and choose what to display, as there is not enough surface area in my house, not to mention our fridge is stainless steal and thus unable to hold a magnet. That is of course, until now. I discovered magnetic paint.
This can of paint has changed the way artwork looks in our house. I started by taping out a section on the wall and then applying the magnetic paint. Be warned! The product says 3 coats will do...not likely. I used about 12 to get the desired magnetic strength!
After I let it dry, the scary black color had to go. So I repainted my wall the original paint color and the look is now seamless.
