T-shirt ties are very handy, but we're concerned they won't hold up to the repeated washing these will face when used in a health care setting. Health care providers also expressed concerns that the stretch may affect fit, as far as the mask becoming loser and less secure over the time of wear.
If you've already made them, they'll be appreciated! Please go ahead and send them to us.
But please consider grosgrain ribbon or making your own fabric ties for future masks. T-shirt ties are absolutely fine for home use or masks that won't be washed every single day at the highest heat settings.
We recognize that right now, many materials are in short supply as normal distribution systems have been disrupted. So being creative with masks made for friends and family is an essential component of this project.
