Silkworms spin silk, the answers in the name.
one silk worm can only spin about .5 of an in and sometimes more. in fact, a large one can spin enough to be wrapped around the tips of your fingers. It takes the silk almost forever to spin just that little so just think about how many silk worms they would need to make a silk dress! But, because China and Japan had so many of them. Other countries wanted this, so China traded silk during 300 BC on the Silk road.
Spiders spin webs with their silk and also use it to wrap up their prey.
They make silk...when the spin their cacoon
Silk is not made out of silk worms. Silk is made by silk worms which spin to make a cocoon for themselves.

There isn't technically a silk plant. Silk worms make silk. They spin a cocoon and silk comes from the fibers in the cocoon. Linen is made from the fibers of the flax plant.
it is originally from these type of worms called silkworms and the silk comes from the webs made by the worms.
Yes they do. Although they don't spin a 'classic' web, they do trail silk as they walk so they can always find their way. Tarantulas that occupy burrows also lay 'trip lines' of silk outside so they know when potential prey is approaching.
No, butterflies form chrysalids but some species spin silk onto leaves to form a hibernaculum out of the leaf.
Aside from cheating, spin a lot of silk.
