This quick and easy to follow tutorial video will show you how to sew a reusable face mask with a filter pocket. I have 3 different styles of masks to choose from depending on what your needs are. This is the perfect pattern if you’re looking to BATCH sew medical masks for hospitals. These masks also include a flexible nose band, do not use elastic, and the tie straps are replaceable if they break. Made of 100% cotton so they are washable and reusable.
