A little late for Christmas, but finished nonetheless:
The pattern is Veronik Avery's Lace Ribbon Scarf available, for free, on Knitty.com. I used Handmaiden fine yarn 'Silken' - 2 skeins - in this lovely bright berry red colour.
The pattern is a simple knit that is easy to memorize. Be warned though -- the recommended length for the scarf is a whopping 80 inches! Mine is just a touch shorter than this as I stopped when I was out of yarn from the 2 skeins.
I'm thrilled with the end result. As is my Mum who received the belated gift.
Hope you all had a Merry Christmas!
