I just finished this Lace Shawl from Knit Picks and it's lovely. I did it in Lagoon Heather, but it would be just gorgeous in white, although in the yarn on the site there is only a Cream Color. This yarn is 100% Baby Alpaca so I'm sure you can find it in white somewhere else.

Just scroll down and you can download the free pattern.
This was my first attempt at a Lace Pattern and it's very easy and knits up pretty quick.
Hope you like it.
