Fabric Mask

This fabric mask pattern has been developed especially for our local school district food service workers.  Please note that we do not represent this as a medical mask but it can be helpful for many situations.




Before You Start:

  • This pattern was designed for homespun fabric which will shrink about 8-10% in the first wash.  If you are not using homespun, you may want to adjust the dimensions of the fabric cut.
  • This pattern calls for a light weight interfacing layer in the middle.  This is not required but it is desirable as an additional filter.
  • Different elastics can stretch differently.  You can adjust sizing to personalize by adjusting the length of the elastic.
  • Always instruct users to launder the masks daily.
  • Please instruct users to be diligent to wear the mask properly by always keeping the outside facing out toward the public.  Mixing up the inside and outside of the mask could compromise the effectiveness.


Materials Required:

Large size mask: 

  • 13" x 12" unwashed homespun
  • 11.5" x 5.5" light weight interfacing
  • 1/4" wide elastic; 2 pieces 9.5 inches long

Medium size mask: 

  • 12" x 11" unwashed homespun fabric
  • 10.5" x 5" light weight interfacing
  • 1/4" wide elastic; 2 pieces 9 inches long

Small size mask:

  • 11" x 10" unwashed homespun fabric
  • 9.5" x 4.5" light weight interfacing
  • 1/4" wide elastic; 2 pieces 8 inches long

Assembly Instructions:

  1. Fold the cut fabric piece in half lengthwise and pin. (Fold the longer edge)  Stitch 5/8" seam from the edge opposite the fold.  Leave the other two sides open as shown in the pic.


  2. Turn to put the raw seams on the inside and press flat with the seam on one edge and the fold on the other.


  3.  Check to confirm that your interfacing piece is approximately 1/4" smaller than the mask on all side.  Trim if needed.  


  4. Insert the interfacing piece into the mask.  Center it 1/4" from the edged and pin in place.  This is an additional filter will will help the mask be more effective.



  5. Serge or zigzag the raw edges on the short sides.


  6. Fold in approx 3/4" of each serged or zigzaged edge toward the center and press.



  7. Stitch the two folded sides down leaving the ends open  This will make a casing for the elastic.



  8. Using a bodkin or a safety pin, thread the elastic through the casing on one side. Repeat on the other side so that both casings have elastic.


  9. Stitch the raw edges of the elastic together on both ends.



  10. Pull the stitched part of the elastic inside the casing and stitch through one opening of the casing and the elastic to lock it in place.  Do this on both ends of the mask.


  11. Gather the fabric up on the elastic until the gathered space is about 2.5-3 inches.  Stitch the elastic and opening again on the open side to lock in place.  Also do this on both ends of the mask.   NOTE- Don't stretch the elastic too much inside the casing when stitching to lock down.  That could make the elastic too long when the mask is worn.




  12. On the inside of the mask, (that's the side with the casing zigzag/serging), use a permanent marker to mark an X to identify the inside.  Please instruct all mask users to ALWAYS put the mask on with the X on the inside.  If users are not consistent with this, it could compromise the benefits of the mask.


  13. Please launder the masks before using them so that they will shrink and fit appropriately.  Machine wash warm/ tumble dry.
