In order to practice for engineering interviews, I bought myself a small whiteboard for my apartment. As I got more comfortable using it, I've come to find it indispensable. Now, I prefer it to pencil and paper as writing and erasing the old fashioned way seems too laborious. I like the effortless flow and removal of dry erase ink even better.
So, to support this new affection, I took to carrying a small whiteboard around with me in my backpack. But even though it is small, it takes up a significant chunk of space in there. What I really wanted was some sort of 'whiteboard notebook' with whiteboard pages. Maybe it exists out there, but I decided to try and make one in the spirit of instructables.
I tried some approaches which failed. First I went looking for some vinyl fabric thinking that that glossy white patent leather plastic stuff would be the perfect whiteboard surface. Not finding any at the fabric store, I tried a cheap $2 shower curtain liner from Target. To my dismay, the whiteboard ink would not erase from it! I guess it has a very fine texture which was enough to grab and hold the ink. Then I tried ironing some clear vinyl which had the desirable whiteboard-like surface effect over the white vinyl. The two vinyl sheets stuck together well enough, but after ironing, the clear vinyl no longer had the whiteboard property and I couldn't erase the ink off it!
I tried another approach of recycling the hard flat plastic shell that came with some packaging. I cut it into squares as evenly as I could, poked holes with a hole punch in that and separated the plastic pages by sheets of plain white paper. I joined the holes together with links removed from a chain. It worked, but turning the pages was awkward and the holes kept breaking free.
Then I had a duh moment and realized I was trying too hard. There is a much simpler answer and here it is. As it happens, some other great minds here have had similar ideas. http://www.instructables.com/id/Low_Cost_Lettersize_Office_Whiteboard/.

I guess I've taken it a little farther and made it into a notebook.
Now all we need is someone to invent a DIY dry erase marker ink in a refillable pen. I wonder how that could be accomplished?
Hope you find this idea useful.
