As Mike suggested - use the examples in your textbook. I just want to add, that when i started learning kana i used to write it neatly and it resembled type font. But after getting used to writing kana in a pace as fast as latin or cyrillic script - i noticed some strokes becoming broken as well as other changes. Also my そ used to turn out ugly so i switched to
which feels much more comfortable to write to me.
Oh, and one more thing - i also had those doubts about whether my handwriting is "correct" and eligible when i write it in a relaxed manner, comfortable to me. Then one day i borrowed this book from Moscow branch of Japan Foundation and all my doubts dispersed.
