Step Lines

+[title] Turn the mask inside out
+[* black] Carefully ***turn the mask inside out***. The stiffness of the interface material might make this a little difficult. Go slowly.
+ [* icon_caution] Be especially careful ***not to tear the interface material*** while doing this, especially at the two inner sharp angles (marked with arrows).
+[* black] ***Flatten the mask***. Run your fingers along the inside of the seam to push it all the way out, then press the seam down to flatten it.
+ [* icon_note] You probably won't need to iron the flattened seam, as long as the interface material that you're using has enough stiffness.
