Look up "Quilt as you go". There are several different methods. One is where you do it with sashing between. Another is where you do it in sections and connect them without sashing - which is what you are describing. There are several really good youtube videos on both.
For your description, I would look up: Quilt as you go without sashing
I just tried it and a ton of youtube videos came up.
Also look up: Quilt as you go in sections - a lot of videos come up with that as well.
