Be careful. Extra needle holes for decorative stitching destroys the integrity of the shield. You wouldn't make a mask out of cheesecloth would you? The virus particles are minute.
I have these.
Dilicia These are soooo Cute!, Hugs, Judy...
Mary, I have several models and I can send you. Facebook or email. Can I donate here? I don't know how to post. kisses
Maybe embroider a small butterfly or hearts etc just on the outside panel of the mask so that there aren't extra holes through the whole mask and then perhaps iron on a fusible interfacing. And of course if it's just fabric there are so many prints that would lend themselves to girly masks.....unicorns...princesses....etc. Just as there are plenty of prints for boys as well.
There are many free masks about on embroidery sites at the moment. Personally I prefer effective rather than cute. My husband and I are making scrubs for our local doctors.
Me too Caroline, effective is most important. You can always use a girly fabric.
