The “MakerMask:Cover” is made from a single layer of spunbond non-woven polypropylene (NWPP) and is designed to be worn on top of other masks: 1) to prolong the use of commercially available N95s, 2) to help contain the users respiratory droplets (i.e., for source control) when used with N95s containing exhalation valves, or 3) to provide a water-resistant layer over cloth or fabric masks.

Materials and Tools

Pattern

• Clean spunbond nonwoven polypropylene (NWPP)

Head Ties/Straps (e.g., bias tape, cloth, or silicone ties)

• Sewing machine

• Thread

• Scissors, clips or pins, etc.

Instructions

Step 1: Print and prepare the pattern

Print out the mask pattern on Letter-sized (8.5″ x 11″) paper. Verify that the measurements on the reference square are accurate.

Cut the pattern out.

Step 2: Cutting

Fold the fabric in half. Place the pattern on the folded edge where indicated. Cut mask pattern out of the fabric.

Step 3: Sewing mask body

All stitching 1/8 inch from the edge.

  • A. Top stitch the two sides together from the fold (top, center) to the top edge of mask
  • B. Top stitch the two sides together from the fold (bottom, center) to the bottom edge of the mask.
  • C. Open the mask; fold left edge over (C, left) and top stitch side to finish edge. Repeat for the right side (C, right).

Step 4: Sewing the straps

Note: These instructions are for double-folded fabric tape material creating the strap. If you don’t have bias tape, you can make your own straps.

Cut two 36″ (91.4cm) long pieces of 1/2″ (1.2cm) double-fold bias tape for the head ties. Unfold the bias tape and position the middle of the tape to the middle of the mask. Sew to the inside of the mask cover, 1⁄4 inch from edge. Fold the bias tape over to the outside of the mask and top stitch the full length of the tape to make finished straps. Repeat for the lower edge of the mask.

• Note: We stitched a “T” onto the top strap to indicate the top

Disinfect/Sterilize before use

While autoclaving is ideal, home users can submerge the masks in boiling water for 10 minutes.

Where do I donate my masks?

It’s really important that in our efforts to get masks delivered quickly, we also do it correctly. We are working with agencies to create a solid distribution network for the MakerMask project so we can provide clear direction on what to do with the masks you produce.

In the meantime, we ask that you work responsibly within your communities to get the masks to a group that can distribute them where need is greatest.

Please follow the guidelines below:

DO

Do verify that the healthcare providers and other front line workers want what you have to give.

Better yet, before you make, check with them, and make what they want.

Do include labeling information with all face masks.

DO NOT

DO NOT DROP OFF MASKS RANDOMLY at medical facilities. It does more harm than good.

DO NOT CALL AROUND TO HOSPITALS OFFERING MASKS.

Before you start, check with your local and social networks, as well as the resources below to find out what facilities and groups are asking for:

 

Spunbond nonwoven polypropylene (NWPP) Bags

Despite being called “non-woven”, NWPP is pressed with a cross pattern that gives it a woven appearance. A common source of NWPP is reusable shopping bags.

Look for reusable grocery bags with a cross-hatch pattern, no insulation or waterproofing. Make sure materials are breathable before use. NWPP bags can be safely laundered. For additional information see: The Big Four: Criteria for Community Mask Materials.

 

Fabric Ties

page4image1249472992For securing the mask to the face, bias tape is a great option and commonly found at craft stores. Alternatively, ties may be fashioned from clean strips of NWPP or other available material that is machine washable and long enough to tie around the head. Elastic may cause severe reactions in individuals with a latex allergy, does not generally hold up as well to the heat of sterilization, and therefore should not be used.
