Which side should tassel hang before?
Traditionally tassels are worn on the right side and moved to the left during a special portion of the ceremony for high school graduates. For college graduates, Bachelor again wear tassels on right side until their degrees are conferred, then move to left. Graduate students wear on left from the beginning.
How much yarn does it take to make a tassel?
The amount of yarn you need will depend on the size and thickness that you want to end up with. I needed about 25 feet of yarn for my tassel. Cut the yarn off at the bottom of the piece of cardboard, after your last wrap.
