Exodus 36:8-18

8 All the skilled craftsmen among the workers made the inner tent with ten sheets made from fine linen yarn and violet, purple, and bright red yarn. An angel design was creatively worked into the fabric.
9 Each sheet was 42 feet long and 6 feet wide--all the same size.
10 Five of the sheets were sewn together, and the other five were also sewn together.
11 Then they made 50 violet loops along the edge of the end sheet in each set,
12 placing the loops opposite each other.
13 They also made 50 gold fasteners. They used them to link the [two sets of] sheets together so that the inner tent was a single unit.
14 They made 11 sheets of goats' hair to form an outer tent over the inner tent.
15 Each of the 11 sheets was 45 feet long and 6 feet wide.
16 Five of the sheets were sewn together into one set, and the remaining six into another set.
17 Then they made 50 loops along the edge of the end sheet in each set.
18 They also made 50 bronze fasteners to link the inner tent together as a single unit.
