Welcome!
There are many different methods of doing QAYG (quilt as you go).
One brings the back fabric to the front and finishes off the block which are then sewn together.
Another attaches the blocks with sashing strips. I use a variation of this method.
Both give you very different looks on the front AND the back.
I can't tell from your post which one you're looking for or which might be more appropriate.
fwiw, I use a similar method to Kimberly's. Here's her very detailed tutorial full of great step-by-step instructions and tons of pictures.

If you can post a picture of your blocks as they are now, you can probably get more focused advice.
It's a great technique to know.
