How to make a medical mask

Draw a 15 x 12 cm rectangle on the paper. Divide it in half across with a straight line. On the right side, make a mark at a distance of 4.5 cm from the top corner and 3.5 cm from the bottom. On the upper and lower sides of the rectangle, place dots 3.5 cm away from the left side. Connect the marks with smooth lines, as in the photo.

Cut out the resulting part. Using a template, cut out two mirror details from the fabric, leaving them for seams 1 cm from the oblique edges and 3 cm from the straight one. Follow the lines of the template with a crayon, marker, or pen.

Cut the template along the center line into two parts. Use each template to cut out two mirror parts. Along the oblique edges, leave 1 cm of fabric for the seams, along the straight narrow ones — 3 cm, and along the wide ones-4 cm. If you find it difficult, watch the detailed video instructions below. The lines around the template should be visible.

In total, you will get six pieces of fabric. Fold the two largest ones together face-in. Sew along a long curved line. From the edge of this side to the seam, make many vertical incisions. Turn out the part.

In the same way, sew the other two identical parts. Also make incisions on them and turn them out.

The lower edges of the last two blanks are turned up twice by 0.7 cm, smoothing the fabric. Then sew the curved edges.

To the middle of the upper edge of the first blank on the inside, glue a piece of double-sided tape and attach a wire to it.

You have three blanks: the largest one with a wire (the front part of the mask), the back lower part, and the back upper part. Apply the top one to the front with the front sides facing inward so that the raw edge touches the edge with the wire (it will be on the other side of this part). Secure with clips. Similarly, attach the back lower part to the front.

Sew the workpiece along the long edges, removing the clips in the process. Do not forget that you need to stitch along the lines outlined using the template. Before the seams, make a lot of vertical incisions and turn the future mask out.

Straighten the bends, fix with clips and sew. Zigzag along the sides.

Narrow edges bend from the inside to the center by 1 cm and sew. In the resulting holes, insert the same strips of cord or tape. If desired, put on restraints. Tie the straps in a tight knot and hide them inside.

Insert the filter into the hole on the inside of the mask.

What to consider

World Health Organization it is recommended to wear a mask in two cases:

1. If you cough or sneeze.

2. If you are healthy but have close contact with a person with these symptoms.

No mask can protect you completely. But it will reduce the risk of infection if you wear it correctly, as well as regularly wash your hands with soap and water or treat with an alcohol-containing antiseptic.

The material from which you plan to make a mask must be:

1. Breathable. This is necessary so that you can breathe freely, and the face under the mask does not sweat.

2. Not rude. First, the rough fabric will irritate the skin. And secondly, it will not be able to repeat the shape of the face, that is, the mask will not fit tightly to the skin.

Try not to touch the mask while it is on your face. If you have to do this, be sure to wash your hands before and after.

As soon as the mask becomes raw (usually within 2-3 hours), replace it with a new one. Ideally, you should change the mask immediately after you have sneezed or coughed inside it. To do this, you should make several masks and carry them in a pack with you.

In no case do not wear the same mask for longer than a day

Fabric masks should be thoroughly washed in hot water with washing powder. It is not yet known at what temperature SARS‑CoV is destroyed‑2. Its closest relative SARS-CoV, which causes atypical pneumonia, died when heated to 56 °C within 15 minutes. Therefore, the hotter the water, the better.

After washing, when the mask is dry, iron it with a hot iron. The well-ironed accessory will be softer and will sit on the face tighter, without folds.
