Over the course of sewing 350+ Olson masks, I’ve developed some shortcuts to streamline the process. My goal is to make well-fitting masks as efficiently as possible. I have not made changes to the shape or size of the original pattern pieces or material recommendations. I do not and cannot make any claims as to how these changes may alter the effectiveness of the mask.
