I always get Alpaca often confused with the llama how can you tell the difference?
I think alpacas are smaller than llamas. 
I love how fluffy they are they auction them off a lot and the cost for one is sky high.
Yes that alpaca fiber is so soft! It's used to make all kinds of things like blankets and sweaters. 
So thats why they sell them for so much because that person can make a good product profit off of them they can go for 750,000 the sweaters better keep my whole family warm lol.
The alpaca fiber is warmer than sheep's wool, and it is also hypoallergenic. Maybe that's why it's in high demand and so pricey.
