Fauziah Coffey has produced dozens of the bands which have buttons attached. The ends of the masks can be looped around the buttons.
The 59-year-old teacher is offering them to health workers or NHS trusts and is urging them to get in touch.
Mrs Coffey said: "My daughter is a GP but she sometimes has to go to A&E at Princess Royal Hospital in Telford.
"She said her ears hurt after an hour of wearing the elasticated mask.
"She took some of the mask bands to work at A&E and it proved to be helpful. All bands were taken.
"I have spares and quite a lot of yarn but the problem is getting hold of the buttons."
Anyone who can help her source buttons that are about half an inch wide are also being asked to get in touch.
She has also been crocheting hats and blankets for premature babies which she wants to give away.
