Exodus 36:8

And all the wise in heart made the TABERNACLE; ten curtains of fine linen, and hyacinth, and purple, and scarlet, figured with kerubin, the work of the embroiderer, he made them.

AND EVERY WISE-HEARTED MAN AMONG THEM THAT WROUGHT THE WORK, MADE THE TABERNACLE OF TEN CURTAINS. The Torah has repeated the [description of the] work of the Tabernacle five times. — Chapters 25-27, and in parts of Tetzaveh]. 2. In a general way [in the section of Ki Thisa — 31:6-11]. 3. At the time of the actual making thereof — in a general way [at the beginning of this section — 35:10-19]. 4. Specifically at the time of construction. For even though this is not mentioned expressly, yet Moses surely told them details, such as that the curtains should be of such and such a length, etc., as will be explained by Ramban further on. 5. The specific account of how each part was made [beginning with our verse here]. It mentions the whole of it at the time of the command in detail, and in general terms. First it says, “and you shall make it thus,” “and you shall make it thus,” and then it mentioned all things in a general way, and they will make all that I have commanded thee: the Tent of Meeting, and the ark of the Testimony, until according to all that I have commanded thee shall they do., Verse 11. The reason [why the command is repeated in a general way], is that G-d commanded Moses that he should tell Bezalel and Oholiab and all the wise men about the work in general terms, and only afterwards should they begin to do it, for they would not be suited for the sacred work until they had heard the scope of the whole undertaking and understood it all, and only then could they accept it upon themselves, when they know how to finish it. At the time of its actual construction he described it to them first in the general way as mentioned here, saying, let every wise-hearted man among you come, and make all that the Eternal hath commanded: the Tabernacle, its tent, etc., 35:10-11. This is the third time (see Note 55). The statement of the details is, however, missing here; for surely Moses had to say to the wise men who did the work: “make the Tabernacle of ten curtains, each curtain of such-and-such a length and such-and-such a width,” and so on with the whole work. This procedure [of Moses’ telling the workers the exact details of the measurements] Scripture does not mention, for it is understood that he told them everything in order, since they made each part exactly as prescribed. And the reason why Scripture does not mention it is that it was not necessary for Moses to go with them into the smallest details as they …

ויעשו כל חכם לב; first they fashioned the Tabernacle itself; after that they made the furnishings, etc., as I explained on Exodus 25,10.

ויעשו כל חכם לב בעושי המלאכה, the most qualified among them built the Tabernacle (components) which involved weaving shapes of figures into the cloth so that they could be seen both on the outside and on the inside. (compare Yuma 72) These “curtains” were not thick as was the dividing curtain, פרכת. This portion repeats everything that has already been mentioned in connection with the instructions in Parshat Terumah. The reason why the Torah repeated all this is to inform us that when it came to the execution of the project they did everything so as to correspond to G’d’s will and to bring it to conclusion and make it functional as G’d desired. הארון, seeing that the Ark was the most distinguished of the furnishings of the Tabernacle, Betzalel, the master craftsman and architect fashioned this item personally. The sages say of Betzalel that he was capable of using the letters of the alphabet of the Holy Tongue in a manner similar to the way G’d had used them when creating the universe. (compare Berachot 55)
