I have just, super quickly, made a facemask from a pattern by one of our Knitting & Stitching talented tutors Katya Essery, Sew Pretty. She has designed three sizes of this simple mask for women, men and children, which is made with minimal fabrics and really is easy and fast to make.
The only difference I made (being a bit pedantic!) is I trimmed the outward curved seam allowances down, cutting small wedge shapes out of the seam allowance so it lays more smoothly. I also used beading/hat elastic which is very fine so shouldn’t be too uncomfortable around the ears. I cut two pieces of 20cm, tying knots at the end of each. These I then inserted into the side edges of the face mask and as Katya suggests in her instructions, stitched along the edges, closing the seam and capturing the elastic. The knots will prevent the thin elastic possibly being pulled out through repeated wear.
And the thing is, I used remnants of dress fabrics, so if this does become an obligatory fashion accessory in future, I can make them to match my outfits!
