* I only wear the mask for extra protection on my face when riding motorcycle/motorbike (that’s why you see a helmet on the fist picture), I had no intention to use it as protection against covid *

It’s a very simple project, performing German short rows and simple decrease for shaping and attached I-cord on it’s corners. This project is a perfect choice to use up your leftovers yarn, which is only worked for 44rows in total.

Edit:
For more safety, you can add additional layer, then put paper tissue or cotton fabric inside.
