Not to be rude, but did you have a typo when you stated that you had 336 geese, one for each day of the year? You mentioned the leap geese so I was figuring it must be a typo.
There are actually 365 days of the year, except on leap years when we have 366.
Either way it is a very pretty quilt. You could always tell your sister that you put the couple of flights of geese in the wrong direction for good luck just as the Amish do. lol
