Start with a piece of felt, about an inch and a half width. Length is up to you. The longer, the bigger the flower.
Next, fold the yarn in half- hot dog style. Seal the edge with hot glue.
Then, using scissors, make small cuts into the felt on the folded side (not the side with hot glue).
Then start at one end and begin to roll. At the end of the roll, put a small amount of hot glue to keep the flower closed.
Then you are done!
