Fairfield OLY Fun Multi-Purpose 20-Inch Craft Material, 3-Yard, Bubble Gum

This is a very good breathable filter for masks. It isn’t made to put on the hot dryer or to be ironed. It will melt.

This is a great interfacing. I am using it as an interfacing for the masks I am making during this coronavirus.

Used to line face mask, worked great

Used this as a layer of a mask

I used it on the inside of masks- between the outside and the lining... its washable and the fibers are dense enough to give great protection according to guidelines. Do not use high heat directly on product, or very hot dryer. Comes in great colors!

I bought this to line my face mask on recommendation of a owner of a quilt shop who is also a retired Nurse. The material acts as water resistant layer and is not woven so better protection against very small particles. It also acts as a nice interfacing and helps the mask keep its shape. It also can be washed and dried. It did not lose any of its supportive features. It’s also light weight and am able to breath but feel better protected with this extra layer of protection.
