Pile of socks (some assembly required)

So, you want to see what Santy Claus brought me?

Let's see, from left to right, top row is some alpaca and some Cherry Tree Hill Supersock in eyeball-popping Fall Foliage...bottom row left to right is LL in Desert Flower, LL in Amish, Lang Cotton in 0052 and Trekking in 116.  Now, the obvious problem with sending Santa out to buy yarn is that now Santa knows how much yarn costs.   He didn't mention it, but I'll have to be sneaky with my purchases, LOL!

Anyone knit socks from alpaca?  Anything special to know?  I thought about knitting the foot in something else and knitting just the leg in the alpaca.  The woman at the shop where he bought this told him to carry wooly nylon with it, but does that really work? 

Happy Boxing Day!
