Sewing/appliquéing pawpads

I'm not sure how to properly sew paw pads onto paws with the sewing machine, and every time I try, it's off. I can't see my line clearly even if it's charcoal pencil on white because the presser foot always blocks the view of it, so if you'd please share your technique I would be ever so grateful.

I couldn't find any tutorials or specific techniques. If there's a post I missed about it, please link me there. Thank you so much.
