I can’t really call mine a whiteboard, because it’s blue…or a dry-erase board, because I use non-smear ink pens which need to be erased with a damp cloth. It’s magnetic too, which puts it in an entirely different category. All I know is whatever this thing is, I LOVE it! It’s incredibly useful when you’re in the midst of writing a novel–for plotting, keeping track of facts and timelines, inspiration–you name it. Especially when you live in a New York City apartment where space is at a premium and your office is, literally, a converted walk-in-closet. Hanging a magical board on the door expands the work space. TAH-DAH!

For a previous book I was working on, I used a virtual “canvas service” called Lino for basically the same purpose as a dry-erase board. (A novel approach! Pretty impressive. Kinda fun.) 
The advantage is you can create as many online boards as you like and include links to videos and documents. (Space-saving. Transportable. So, what’s not to like?) Well, the downfall, for me anyway, is you have to view these boards on your computer, and my 23-inch screen is already jam-packed with my manuscript, notes, maps, pictures, etc. When I’m in the “sacred zone” of writing, I don’t have the patience for the 1/100th of a nanosecond it takes to click on a link and wait for something to load. I simply want to glance to my right and see the info I need immediately. (Or my left. I’m flexible.) “A tangible board that’s right there in your face at all times?” you ask. Yes, please! Not very high tech, I know, but the heart wants what it wants.
Traveling back even further in time…I remember using prehistoric index cards taped to my door to keep track of plots and timelines. A crude approach, as there was no rearranging them without having to replace the tape and pulling up paint chips. Eek! (It was a different world. We didn’t know better back then.) Post-It Notes to the rescue! The problem with these little beauties is they don’t stay up for very long. Even the new and improved super-duper strength Post-Its will eventually come fluttering to the ground like sleepy butterflies and wind up stuck to the soles of your shoes–or the cat.
Not to diss the almighty Post-It. I still use them for many different things–but for this specific purpose, they’ve been happily replaced with something called mcSquares Stickies Dry Erase Notes. A tad expensive but they’re durable so you can rearrange them at will–plus they come in different shapes and sizes. (I swear I’m not a spokeman for the company–just a fan. There are other brands out there as well, like SlickyNotes that come in different colors!) These things stick to most smooth, flat surfaces so you don’t even need a whiteboard–or blueboard–or whatever. I find that the non-smear variety of markets work best in this scenario. (Tackie Markers and Writey Liquid Chalk are my faves. Again, not a spokesman.) You’ll need to use a damp cloth instead of a dry-eraser with these but it’s so worth the iota of extra effort.
So, that’s the scoop. Carry on and HAPPY WRITING!
Unabashedly Bonk!
