I think you create the ominous mood of this description well. The "black stitches" immediately indicate the darkness of the poem and the ending "so no // one knows she's screaming" is horrible (but in a good way, because I think it's meant to be).

Your use the run-on lines effectively but I don't know if it's necessary to begin each line with a capital letter. It undermines the run-ons a little bit.

Also, I'm not sure about "mould" as a word choice in the first line. I think what you're trying to convey is the sense of someone else creating, forcing this smile on her; but "mould" for me doesn't have quite the right overtones.
