This video looks a bit amateur-ish and the Japanese could intimidate some people, but I tried these steps (with other ingredients) and it's pretty easy. And delicious! xo (p.s. the faca should be a bit wet when cutting the rice)
Personally I like bento and onigiri both equally because their both so yummy and kawaii. Onigiri and bento can be decerated so cute and they both taste so good. Thats why I like them both so much.
