The Slytheirn then slipped her wand off its holster. Kat took a rubbish bag and hung it on her mannequin. There. The bag had slits and cut holes already so it wouldn't be too hard for her anymore.

Positioning herself and finally pointing her wand at the rubbish bag, Kat casted the spell. "Summitto Vestis," she said with the upside down V movement. But no spell took effect on her rubbish bag. Well, that's completely rubbish! Do again.
