Since I am redecorating my little corner in our office, I just happened to come across some washi tape (on sale - yay!) at JoAnn Fabric and Craft store.
I have some fun office projects I want to do using washi tape, as well as some small household projects to pretty up some items we have duplicates of so we know who's is who's item.
If you aren't familiar with what washi tape is, washi tape is typically made from natural fibers, such as bamboo or hemp, but most commonly from the bark of trees that are native to Japan — the mulberry, the mitsumata shrub or the gampi tree. Most washi tapes are strong (as strong as duct tape in some cases!) and functional as well as pretty, making them wonderful for both everyday and decorative use. (source)
