“she’s not using very ‘breathable’ fabric”
I’ve modified my patterns since I started. Used to use the high-count quilting fabric as suggested. And most patterns require at least two, and sometimes three layers. The last/inside layer had a slit to add still ONE MORE layer — a filter. Well, I decided Homey don’t play that, ‘cause Homey can’t BREATHE. One layer. Loose fabric.
I have to wear one for 50 minutes twice a week at physical therapy, and it’s so loose horseflies basically could get through. Hubby volunteers once a week and has to wear one for five hours; his also are breathable.
I’d like to order a couple with messages from Redbubble, but don’t want to give mask companies financial support — although some are great! (Sadly, some contain minor profanity which adults could handle, but probably not kids in case you came across one of them.)
