silk

One silk tie requires 150 Silk cocoons.
One pound of silk requires 2,500 Silk cocoons.
How much silk is in one tie? A tie needs 150 cocoons, so 150/2,500 = .06
That is 6% of a pound, which is .96 ounces, almost one ounce. If that were weed, I would call the cops. Tiny farmers raise 200K to 1 million silkworms at a time. Both are ugly, so I am providing no pics. You can submit a pic of your pretty silk anything.
