This sun rays masquerade mask is printed on tulle which allows it to be flexible and fit to your face.
The design is symmetrical and the little bits of the design on each edge allow you to tie a ribbon on to wear the mask. The mask can also be taped right to your face with double sided tape which makes it look like it is floating or tattoed to your face.
The full tutorial on how to do this can be found here on Instructables.
(If you don't want to, or can't, print it yourself, I'm also selling completed masks on Etsy.)
Designed in Tinkercad.
