Approved Pattern Info for Homemade Masks

The Great Falls Clinic is seeking homemade masks to prepare and offset the limited supplies available to healthcare workers. There are some specific requirements for acceptable masks which are provided in the links below.

While we are spearheading this project, we fully intend to share the masks that are made and donated to other healthcare organizations as the need arises. At this time, we are not aware of any other organizations accepting them locally but will continue to update our Facebook volunteer group page with this information as well. Group help files (if you do not have Facebook): Medical Masks For Great Falls FAQ and Medical Masks for Great Falls Mask Info.

Mask patterns must be followed by using the tutorial video located at the link below. This is the only pattern approved by the Great Falls Clinic at this time.

All homemade masks must have a built-in pocket for a filter to be placed in. Currently there are no allowed modifications for the mask unless there is a low supply of a certain material used to make them.

All masks must be delivered to the Great Falls Clinic Hospital at 3010 15th Ave South, Great Falls front desk as we have limited volunteers available to pick them up.

A Facebook group has been set up called Medical Masks for Great Falls if you or a community member is interested in assisting during this important time.

Additionally, the Great Falls Clinic is accepting some 3D printed masks. The 3D-printed mask has a snap-in section for filtration material that can be changed out as needed. We are asking all those that have access to 3D printing to consider assisting with this effort. Information on mask design for this particular 3D design is posted on our Facebook group page at Medical Masks for Great Falls.

HOW TO MAKE FACE MASK WITH FILTER (we supply our own filter) POCKET AND ADJUSTABLE WIRE – SEWING TUTORIAL – YouTubePattern from EasyToSew on YouTube:

Beginner Friendly Tutorial Video for Sewing Masks provided by Medical Masks for Bozeman:

Considerations: Prewash cotton before you start to see–Fabric of tight weave cotton or cotton/poly and color-fast so when washed in hot water will not bleed.–The nose piece stay is going to be a garbage bag tie and can be stitched in place. You’ll see that in the video.

Material Quantity Dimensions
Cotton or cotton/poly woven fabric 1 15” long x 7.5” wide
Bias tape or 2” width fabric strips 2 **36” long**
Plastic Twist Tie or **pipe cleaner** 1 About 6.5” long

**Based on feedback and requests from the community, these directions have been updated**

  • Serge or zigzag the short edges of your rectangle.
  • Fold your fabric right sides together, matching the short (serged) edges.
  • Mark 1.5” in from each unfinished side.
  • Stitch along your finished edges with ⅜” seam allowance to the mark, reversing at the beginning and end of your seam. Press your seam allowance open.
  • Topstitch one edge of your seam allowance, ⅛” from the fold.
  • Mark ½” above the unstitched side of your seam allowance. Fold your mask at that mark. Press flat. Topstitch around the entire mask, ⅛” from the edge.
  • Important info regarding twist tie: do not use paper wrapped ties (like bread ties). The paper comes off during wash and wads up and the metal material becomes sharp.
  • Insert your twist tie into the top of the mask (above the unfinished pocket edge). Stitch along the top edge of the pocket opening, enclosing the twist tie.
  • Fold three ¾” pleats along your mask **so pleats face down on the front of the mask**. Press. Run a basting stitch along the edge of the mask to hold the pleats.

((For elastic ear loops))

  • **Lay your bias tape or 2” fabric strip right sides together along the edge of the mask. Leave 12” of bias tape hanging below the mask and the rest of the excess above the mask. Stitch in place with a ⅜” seam allowance.**
  • **Fold the raw edge of your bias tape to meet the raw edge of your mask. Fold again so the folded edges meet along the ties, and covers your previous stitching on the mask. Topstitch in place down the entire length of the bias tape (36”). Finshed!**

For elastic ear loops: 

¼” elastic 2 pieces 12” long
½” bias tape or 2” wide strip 2 pieces 6” long


  • Lay your bias tape or 2” fabric strip right sides together along the edge of the mask. Leave ½” above and cut excess to have ½” overhang below the mask. Fold the ½” overhang to the back side of the mask on top and bottom. Stitch in place with a ⅜” seam allowance.
  • Fold the raw edge of your bias tape to meet the raw edge of your mask. Fold again so the folded edge covers your previous stitching. Topstitch in place.
  • Insert your elastic through the channel formed by the bias tape. Tie ends and tuck knot inside bias tape channel. Finished!


  • In place of elastic ear loops, you may now use 1/4″ cloth ties, 1/4″ parachord and or 1/4″ decorative elastic. Some elastic is available in 1″ and 1/2″ and is easily cut and proven not to fray in our tests.
  • In place of plastic ties, you may now use pipe cleaners or flower wire. You may also submit a request via the Facebook group for review/approval if you have a unique material that is washable and not sharp.
  • We are supplying our own filters for our staff. We will not make recommendations to the public on filter use, this is up to each individual.
