Exodus 26:1-5

“Moreover, you shall make the tabernacle with ten curtains of fine twisted linen and violet, purple, and scarlet material; you shall make them with cherubim, the work of a skilled embroiderer.

The length of each curtain shall be twenty-eight cubits, and the width of each curtain four cubits; all the curtains shall have the same measurements.

Five curtains shall be joined to one another, and the other five curtains shall be joined to one another.

You shall make loops of violet on the edge of the outermost curtain in the first set, and likewise you shall make them on the edge of the curtain that is outermost in the second set.

You shall make fifty loops in the one curtain, and you shall make fifty loops on the edge of the curtain that is in the second set; the loops shall be opposite each other.
