OK, I know about some of the things that bring back luck to knitters, but what about beginning a sweater for one person, then giving it to another? And does it matter if the people in question are babies? I began a very cute sweater from Kim Hargreaves' Pipsqueaks a long time ago for a certain someone who was still in utero.
I realized quickly that it was going to be way too big. Yes, they always grow into them, but I wanted to see the kid in the thing before I (forget the kid) got old. So I knit a different very nice sweater in a very nice yarn from the same book and gave it to the child in a timely fashion. This dear little one wore the sweater in good health and is now too big to fit into the original sweater.
May I now finish the sweater and give it to Ellie? Knitters, astrologers, soothsayers, what say ye?
