All in all, it’s worth buying and trying out washi tapes, in my opinion. It’s okay if you disagree with me. Art supplies and equipment are always not very cheap after all.
I’m hoping to share what I know because I feel the same in the beginning as to why these tiny tapes are pricey.
On the other hand, if I compared it with a ribbon, it could be more expensive. Plus, an additional item like glue is needed if you stick the ribbon on the surface.
Anyway, it is vital to find a way to use, if you decide to splurge. If you prefer to collect it, it’s alright too. Regardless of the price, it depends on your interest, decision, and affordability.
