First off... love the product, but I was kind of annoyed by the guy in the review video. He chose the largest size that didn't fit his little space... then he rolled it back up incorrectly and mushed it! Sorry, I get a little OCD with things like that. http://www.5min.com/Video/WhiteyBoard-Portable-White-Board-Review-288682824

With 'Home Design' I usually think of publications like Dwell Magazine. They have a cool blog area online
http://www.dwell.com/blogs/ but if you're thinking about doing any print ad marketing, they also have a section in the back of the magazine called 'modern market'. Check it out next time you're at the news stand.

Here are some 'Home Design' blogs that I found:

I had fun doing this. If you want to use me again... feel free to send me a direct message.
I'd work for a few Whiteyboards! Good luck with your product. I like it!

I would post it to reddit.com, digg.com, and lifehacker.com. They would probably get a kick out of your product - reddit has been known to get innovative and neat products a pretty fair amount of business in the past, especially if you give them some kind of limited-time discount.

If I were to come up with literally the top 10 sites on the internet for each of those categories, i would search through http://www.alexa.com/topsites , http://www.delicious.com , and perhaps http://www.topsite.com/
I haven't actually got time to look through and find the top blogs that fit your criteria at the moment, but perhaps another helpful member of this site can do that for you. Good luck! Neat product, by the way. :-)
