I am ordering some washi tape rolls to start a new chevron theme in my classroom. I love zigzag chevron pattern because it looks so crisp! I also like tiny polka dots but I think that for me, it would be best to stick to one pattern.
I will mostly use it for line borders of different sizes and colors for around my windows, bulletin board display areas, library shelves and white boards. I learned from Pinterest that you can put washi tape on anything, even for smaller projects like customizing classroom stationery - binders, folders, pen holders, etc.
Washi tape is better than adhesive decorative paper rolls because it is made from Japanese rice paper (which gives it that extra thickness and durability).
Here are different colors and styles that are available:
I'm just sharing a few of the ideas I saw on Pinterest, and one of my own, below:
