I wanted to share this really great article that helps explain what exactly Washi Tape is. I'm a HUGE fan of this stuff, simply because it allows me to quickly/easily add layers to my cards and pages. I have to admit that I've also pretty much restricted myself to using it for straight lines only (so far) - but I have plenty to play with thanks to A|Muse Studios' great collection!
