Hey, you can find the scissors in the haunted house. It's a pretty hidden item that will get available once you finish either the child side or the adult side of the mansion. You might need to pull some levers to open hidden doors and backtrack a bit.
I am trying to do as you instructed me, But.... I can't get to the levers because I can't push the crates around
Edit: Nevermind, I figured it out, The Clothing Store guy won't accept the scissors or the needle.
Another Edit: I did as you suggested in the Email, Now where can I find Naoto? I can't find the lass.
Okay nevermind I figured it out now to find the clubroom
