I am a visual person, so, I need to draw almost everything a read for school and learning purposes (molecular biology, signaling pathways, etc.), so, I researched for many items before getting to this paint, which, BTW, was my brother's suggestions. I was hesitant, because there a lot of adhesive white boards, as well as way too expensive "pro" kits that promise a lot. Well long story short, I saw this one here, I read Katy's review and steps, and bought it. I wanted a big part of my basement's wall for this, and so I did. I used only 1 can, 3 layers and about 7x4. Man, I love this "board," if you can call it that. It's great, useful, and well, it was CHEAP! Follow Katy's instructions, and then, paint. You won't regret it. And for writing purposes I'm using EXPO markers, and they are great. NO lines or anything after use. I would recommend the EXPO white board care spray. This helps to keep your board SUPER clean. Great great choice.
