This is beautiful even though I have no idea what a Ruana is (I guess I haven't been at this site long enough to learn what everything is) You have a beautiful soon to be dil. My advice as a mil of both a man and a woman, do what my husband did at my son's wedding. He gave a speech and told everyone "Alicia is NOT our dil, she is our daughter." My dil just found out she is pregnant so I am knitting up a baby storm!
Make sure you post the finished product. We will be anxious to see it.
