Magnetic chalkboard paint and dry erase paint. Your opinion?

<span style="font-size:150"><span style="font-weight:bold"><span style="color:#8000FF">Okay so I switching rooms with my brother :P so that means we get to repaint the rooms XD I CAN'T WAIT!!<br><br>I am VERY artistic and love to have draw on stuff, as of right now my cealing is covered in art work and my desk is covered in art and stuff drawn by my friends (actually on the desk). <br><br>SO I was looking into extending my canvas to my walls. I was thinking it would be extreamly cool to be able to draw on my walls. I was thinking about doing a small section in the Magnetic chalkboard paint combo and then a larger (the only wall with no windows or doors) in Dry Erase paint. Im a little sceptical about doing this because i am tight on money and dont want to waste my money on somthing that wont work that well. <br><br>I have read just 'bout all I can on these two products and so now I am wondering what you all think. <br>Have you used one or both before? Any tips? or just have somthing to say bout this (even if you havent used them before)?</span></span></span>
