- Wash the Halyard material.
- Iron the Halyard material.
- Wet the Halyard material.
- Use many pins. Instead, please use paperclips, sewing clips or alternatives to pins wherever possible.
- Write on the fabric.
- Use pieces of fabric that are ripped.
- Feel discouraged if your mask does not work the first time.
- Use the perforated part of the Halyard material for the mask. The fused edge can be used only for the ties, as pictured below.
- Follow instructions.
- Use different fabric for the ties, depending on what is available. The material must be able to survive for 30 minutes in a 165°F oven. If you are testing materials, please ensure that you check the material’s manufacturer specifications for heat tolerance and use extreme caution.
- Please be aware that the masks must pass fit testing. Both of our prototypes have passed fit testing.
- Tie a heat-safe tag on the mask that the wearer will use for identification purposes.
- Use various types of metal for the nose wire. Please be aware that some metals will become more rigid than others with repeated movement.
- Practice the pattern on scrap fabric prior to using the Halyard material to ensure that we make the best use of this resource.
- Print out the pattern using the setting for “actual size” not “fit to scale.”
