I used to use a full length mirror but as I recently shattered it I was wondering if buying hand mirrors as replacements would be suitable when casting spells or if I should be buying a new full length mirror or the sorts of mirrors that are propped up like picture frames.

Is there ever a need for mirrors to be a certain way for spells or is it fine so long as you have a highly reflective surface?

My apologies if this seems a silly question.
