Make a Mask



On behalf of our BVWHC team, thank you so much for your interest in sewing fabric surgical masks for our frontline healthcare workers. Your time and talent is greatly appreciated and will help to ensure our staff and patients’ safety. Thank you! 

Our main concern is that our masks are functional and will protect our staff and patients.  It is completely fine to have non-matching fabrics, thread, binding strip–but a well sewn mask with no frayed edges or missed seams or “holes” is important.

Home sewers are reminded to practice social distancing, hand hygiene, and not work when sick while producing masks for donation.

*NOTE: The following instructions are for sewing a mask. If you would like a quick, no-sew method of making a mask, see these instructions or this video


In order to make sure the masks are safe and as effective as possible, please follow these instructions closely.

Sewing Pattern:

In order to best serve our patients and staff, we are asking for both standard masks and masks that have a filter pocket. Please use the tutorials below when making your masks, as it is most helpful to use a standard pattern to ensure proper fit and function.

  • Recommended fabric for the outer portion of the mask includes heavier, non-stretch fabric such as denim, duck cloth, canvas, twill, or other tightly woven fabric.
  • Recommended fabric for the inner lining and filter pocket can be other cotton, cotton-blend non-stretch fabric. It can be thinner and softer, but again recommended minimal or non-stretch.
  • Fabric must be laundered in HOT water prior to sewing to prevent future shrinkage.
  • Polyester or other less breathable fabric will NOT work as well, due to moisture produced when breathing.
  • If using denim or other fabric that is being “recycled,” please be sure it is clean and in good shape. Worn or dirty fabric will not be protective.
  • Fabric ties can be sewn on the mask. There will need to be 4 ties (one tie on each of the 4 corners). Ties should be approx. ¼ inch in width, sewn in such a way that there are no frayed edges, and long enough to be tied into a bow on the top of the head (for the top corners) and behind the head (for the bottom corners). Healthcare workers have reported that elastic bands for the ears get painful.



Please enclose completed masks in a closed plastic bag or closed plastic box and deliver to our Boulder Clinic: 2855 Valmont Rd, Boulder.
