Here's a mask pattern and some additional information from Forbes. It also links to the CDC's comment.

> In settings where facemasks are not available, HCP might use homemade masks (e.g., bandana, scarf) for care of patients with COVID-19 as a last resort. However, homemade masks are not considered PPE, since their capability to protect HCP is unknown. Caution should be exercised when considering this option.

This is because the medical industry needs proven methods, and they still suggest homemade masks as a last resort. Maybe we should all be wearing homemade masks in public.
