While Simply Gilded holds a special place in my heart, and undoubtedly wins the award for most collectible washi tape, I think the HP Washi Collab by Simply Watercolor Co is probably my favorite washi set.
I wasn't sure how I'd feel about the pastel shades. When I think Harry Potter, I think bolder colors like navy blue, hunter green, & maroon. But these pastels...so much love...
It's so shiny! (adding a little Viv Wiggle)
