Here is a picture of a tassel
first you cut 1 piece of cardboard
(depending on how big you want the tassel)
Then you wrap the yarn around the cardboard
(depending on how thick you want it)
Then you take the yarn of the cardbourdand you tie yarn about centimeter or so from the top of the yarn
and tie a loop at the top
and you cut the bottom of the yarn
and there you go a tassel!:)
