The “MakerMask: Cover” is made from a single layer of spunbond nonwoven 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.

Instrucciones
Paso 1: Imprime y prepare el patrón
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: Cut fabric for mask cover
Dobla la tela por la mitad. Coloque el patrón en el borde doblado donde se indique. Corta el patrón de la máscara de la tela.
Step 3: Sew fabric to create cover shape
All stitching 1/8 inch from the edge. A,B, and C below correspond to A,B, and C on the pattern.
- 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: Sew head ties to mask cover
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: These instructions create the head ties from double-folded bias tape. If you don’t have bias tape, you can make your own ties from fabric strips.
- Note: We stitched a “T” onto the top strap to indicate the top
Wash/disinfect cover before use
While autoclaving is ideal, home users can submerge the masks in boiling water for 10 minutes.

Include a label with masks made for others
If making masks for other people it is important to include a simple label describing washing instructions as well as a description of the materials used in the mask.

Additional Information About Mask/ Cover Fabrics
Spunbond nonwoven polypropylene (NWPP) Bags
A pesar de ser llamado “no tejido”, PPNT está apretado con un patrón cruzado que le da una aparencia tejido. Un fuente común de PPNT es bolsas reusables.
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:
Lazos de Tela
For 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.
