Since she had already mastered the incantation and knew what Rune she wanted to use, Kat was definitely ready to start carving the Sowilo rune on her desk. The Slytherin closed her Ancient Runes book and kept it inside her slingbag before taking her wand out of her pocket. Okay, let's get this thing done with now. The wand movement was just a point right? At wherever you want the carve to be done. Easy. Kat pointed her wand on her desk, at the center because she wanted it there. She checked first if the angles were right, and that where she was pointing was at the center. Yes, she wanted it to be precise.

HMM. She closed one eye. Yeah, she could work with that.

"Intaglio Sowilo Sowilo Sowilo Sowilo..." Kat started to cast the spell while maintaining the point of her wand. RIGHT AT THE MIDDLE. GUUH. "Sowilo Sowilo Sowilo Sowilo..." She could see the carve on her desk now. She was doing it well. Inner!Grin. It was almost done. Kat can tell. "Sowilo Sowilo Sowilo Sowilo." The Slytherin then stopped chanting when the rune was finally carved on her desk. YEAAAH... it was at the middle. A little bit of effort paid off. She didn't know if she could run a finger over it... but to be safe, she just waited for instructions. For the meantime, she would just admire the rune she had carved.
