31 And thou shalt make a veil of blue, and purple, and scarlet, and fine twined linen of cunning work: with cherubims shall it be made:
32 And thou shalt hang it upon four pillars of shittim wood overlaid with gold: their hooks shall be of gold, upon the four sockets of silver.
33 And thou shalt hang up the veil under the taches, that thou mayest bring in thither within the veil the ark of the testimony: and the veil shall divide unto you between the holy place and the most holy.
We go from the external structure of the tabernacle to internal. The veil being described in these verses would divide the interior of the tabernacle in two. Entering the front curtain (which we will get to shortly), the priest would enter a holy place, but it would be partitioned off from the most holy place by the second curtain which is described today.
This curtain was to be made of fine-twined linen that had been dyed blue, purple, and scarlet, and was to be decorated with cherubim needlework. This detail is exactly the same as what was said for the first layer of curtains that was laid over the top and sides of the tabernacle. That first blue-purple-scarlet linen layer would have been the only one visible from within, thus the ceiling and walls would all match this new dividing curtain.
Furthermore, verse 33 specifies that the position of this new wall-curtain was to be directly under the taches that divided the back half of the outer cover from the front half. I previously discussed possible meanings of those taches, and one of those was that they might have been were to there to provide a distinct separation in the ceiling from the holy place and the most holy. There would be no strand of cloth that ran from the walls and ceiling of the holy place into the walls and ceiling of the most holy place.
Note: It can be difficult to visualize some of the structures described in these verses. Here is an excellent and extremely focused series of animations that show the visual form of the temple and its instruments, built up verse-by-verse from the Exodus record: https://youtube.com/playlist?list=PLpjohncRg94EZ55nJrbaKfi-lfeo3MFgl&si=6wm1J9Sdnu7LKYC_
