Try this...

Pick out a random hydrogen atom in your body. Mentally, go back in time to around 380,000 yrs. ATB and find that atom. Draw a circle around this point about 13.2 billion lyrs. in radius. Now draw a huge circle with a random center where your first circle is enclosed within the larger.

The smaller circle perimeter, with your hydrogen atom center, represents the region we are now observing we call the CMB. It has taken this light this long to reach us and from all directions (as the circle is really a sphere).

The center of the larger circle is erroneous as there is no center but it helps establish the bigger picture, I think.

Is this a fair representation?
