Well, you've probably already figured out, if you follow Elle Decor, that tartan/plaid is big this fall in fashion and preppy checkered prints. This means it's going to trickle down into the interior design world. .
One thing that a lot of people get confused on, myself included, is the difference between tartan and plaid.
From what I understand, everything started with the Scottish. Plaids are pieces of clothing or blankets, no matter what design is on them. The print was usually tartan, so people would get confused and call the tartan, plaid. Tartan is defined as a pattern, and that pattern is of varying colors and varying widths of bands that lap over each other and create right angles. All of this happens over a solid colored background. Did you get that? My brain hurts. Yeah, well anyways, if it looks plaid it's tartan. If you want to call it plaid, it's perfectly acceptable here in North America. There is no difference between the two, (unless you live in Scotland) and really that's all that most of us need to know.
