Apple Notes question

[superfish]

I'm running iOS 9.2.1 on my iPad Air 2. I want to use the drawing function to annotate notes that I have typed into the app. That is: I have a note that I would like to draw on. When I try this, as soon as I click the drawing function I get a blank page. If I click on "done" it puts the drawing on the original page but I can't control where on the page. I have to guess on the placement. Is there a way to draw directly on the note?
