What I notice in Exodus 26 is that the inner curtain, which had pictures of the Garden of Eden with palm trees and cherubim motifs on it, needed to be made by a skilled craftsperson. In fact, nothing in all of these construction plans for the tabernacle could be made without people skilled at various trades. Nor, for that matter, could they work any of the raw materials without skilled and unskilled labor. Everyone was important.
