doodle and write notes on these chalkboard vases

The other day I was just thinking about how much I'd love to cover my dining room table with the white paper. you know, the white paper used on the tables in restaurants to draw on, so I can sketch and doodle while I eat. so when I found these today (via outblush) I just had to get one... or 2 or 3 or... all I need to do is figure out what size/s. they can be found on line here.
