but its the finished edge the makes a yoyo - it has to be a visually finished product from both ends.
i agree that its not necessary to use a yoyo on a drunkard path block or in the jane block. it isn't even necessary to use an applique stitch like the other tute shows.
what you're using is not a yo yo its an applique piece that resembles a yo yo but could not function in the other ways that a yo yo can.
if its not a visually finished product from both sides its technique is not a yo yo.
its not the gathering that makes the yo yo, its not the template that makes the yo yo - its having a finished product that can work from both sides.
