Moreover, you shall make the tabernacle with ten curtains of fine twined linen and blue and purple and scarlet yarns; you shall make them with cherubim skillfully worked into them.
Exodus 26:1

There are ten curtains of the tabernacle in this verse. Perhaps because we are to be clothed in the Ten Commandments? IDK. Unlike our own clothing, the Mishkan's covering was made of interwoven wool and linen. Torah forbids wearing clothes made of a linen/wool mixture.
