This leaf mask is in the same manner as my moon and stars where you print the first layer, pause the print, add tulle, and continue the print.
The pattern is leaves in a symmetrical pattern.
After it's done, you cut out the mask and out the eye holes.
I printed on Ivory Tulle to match my skin tone, but you can go crazy and do any color you want.
Attach a ribbon to each side to tie on. I cut into two holes on a leaf on each end to thread through and attach the ribbon I've also used double sided tape to just tape it to my face so it really looks like it's floating there!
