The 15-year-old decided that sewing her own clothes would help her get into character as she prepares to play tortured teenager Carrie White in the forthcoming horror reboot, reported Contactmusic.
"Learning to sew for Carrie!! I learned 2 weeks of sewing in 2 hours! Made a tote (bag)," Moretz posted on her Twitter page.
The star also posted photos of herself with an industrial sewing machine, as well as a snap of the finished product.
Moretz is sharpening her sewing skills so she can create the dress she will wear in the film's key prom scene, in which Carrie wreaks havoc with her supernatural powers.
