I finished my birthday yarn scarf yesterday and it is beautiful. The pattern is Bluebird Lace Scarf by Kara Peterson.
The yarn was a strand of a yarn from http://www.kingbecky.com/ put together with a strand of very fine silk yarn I already had. The kingbecky yarn is very discretely shaded - beyond the capacity of the camera to show. The result looks as if it has been made in a solid colour but the slight variations catch the light differently so it looks even better in real-life than in the photo!
