Finally I was able to finish a scarf, and it is the first lace scarf I have ever made! The pattern is Tiger Eyes Lace Scarf and can be found on Ravelry for free.
Here is what the design looks like. I used smaller needles than recommended, but it still turned out beautifully. The yarn is Berroco Ultra Alpaca Fine in colorway 1207. I blocked this scarf on folded up towels, so wasn't able to stretch it much. Someday I will have those gridded blocking foam boards to do this with!
I am using Patons SWS in Natural Garden for this scarf, and plan on knitting through 3 balls. The picture below is about 5 days old, and now I have finished the first ball. A modification that I made to the pattern was decreasing the number of squares by only casting on 16 stitches (instead of the 24 that the pattern called for).
