Table relationship and subform help for a beginner

I have a Projects table that has multiple notes with each project. I have a Company table with multiple notes with each company record and a Contacts table with multiple notes with each Contact record.

I want to create a Notes Table with NotesID, Date of Note, and Note as the fields but am having trouble putting the relationships together properly.

My end goal is to have the Notes show up as subforms on each of the Projects, Company, and Contacts Forms and only the notes that are specific to each of those records even though they are in different tables.

I have a NotesID field in each of the other tables and link it to the Notes table by NotesID. I've tried this several different ways and don't get errors but get different results than what I expect or don't get any results even though I have create notes already. So I would like to work through this from the beginning if possible. Thanks for the help.
