Exodus 36:8-13

8All the skilled craftsmen among the workmen made the ten curtains for the tabernacle. They were made of finely spun linen, as well as blue, purple, and scarlet yarn, with cherubim skillfully worked into them. 9Each curtain was twenty-eight cubits long and four cubits wide;1 all the curtains were the same size. 10And he joined five of the curtains together, and the other five he joined as well.

11He made loops of blue material on the edge of the end curtain in the first set, and also on the end curtain in the second set. 12He made fifty loops on one curtain and fifty loops on the end curtain of the second set, so that the loops lined up opposite one another. 13He also made fifty gold clasps to join the curtains together, so that the tabernacle was a unit.
