Very unscientific survey!

Well here is a conundrum! In my earlier post today, I was trying to decide on the orientation of the maple leaves on my Come Fly With Me quilt. Then Cindy (bless your little heart!) asked if leaves fall with stems up or down? Such a good question, so naturally I went outside and shook my ash tree which is already losing it's leaves. I had to know! Unfortunately, the ash has really no stem to speak of, so they just kinda spiraled sideways! Question remains unanswered! So what do you think? Or do you know for sure which way they are supposed to fall. Maybe for clarification, I should add that there is no wind!
