You've waited many weeks to find out, but now here it is! Capt'n John has discovered the Number One Most Expensive Fabric in the world. Have you figured out what it is yet? Click through to find out!

Did you guess what it was? The #1 Most Expensive Fabric in the world is Vicuña, which comes from the vicuña, a relative of both the llama and the alpaca.

Here is why Vicuña is the #1 Most Expensive Fabric:

"Are you looking for the ultimate luxury fabric? Look no further than the vicuña. This rare and precious fabric comes from a cute and cuddly animal that roams the high Andes mountains. But don't be fooled by its cuteness – vicuña fabric is one of the most expensive fabrics in the world, and for good reason.

The vicuña is a relative of the llama and the alpaca, but it's much smaller and more delicate. It has a soft and silky wool that's highly prized for its quality and rarity. In fact, vicuña wool is so precious that it's been protected by Peruvian law since the time of the Incas. Only a limited amount of wool can be harvested each year, and it must be done by hand.

So, why is vicuña wool so expensive? For starters, there are only around 350,000 vicuñas left in the wild, and they can only be found in the Andes mountains of Peru, Chile, Bolivia, and Argentina. Because of their endangered status, vicuñas can only be shorn once every three years, which limits the amount of wool that can be produced. Additionally, the process of harvesting the wool is time-consuming and labor-intensive, which also adds to the cost.

But despite its high price tag, vicuña fabric is highly coveted by luxury fashion brands. It's incredibly soft and lightweight, yet it's also incredibly warm. This makes it perfect for creating high-end coats, scarves, and shawls. Some of the most famous fashion houses in the world, such as Hermès and Loro Piana, use vicuña wool in their designs.

So, what are some fun facts about the vicuña and its wool? For starters, the vicuña has the finest wool of any animal in the world, with fibers that are only 12 microns in diameter. It's also incredibly resilient, with wool that can bounce back to its original shape even after being stretched or compressed. And because of its delicate nature, vicuña wool can only be spun by hand.

As with all uses of animals, it is important to make sure you are buying from a source that treats the animals ethically."
