?? I only know onigiri is the triangle riceball! This is the book
this is the author Kimiyo Fukuda and look at her workshop!
This book contains detailed step by step guide on how to make this triangle shaped bag (inclusive of interfacing, inner lining, making the pocket and handle). There is also a section on pairing the outer and inner fabric.
Interesting ideas to jazz up the bag
Lastly, a section on boy/man bag.
The patterns inserts were torn away : (
Nonetheless, I will never look at onigiri the same way again!
