lay the napkin flat and facing you in a diamond pattern

take the top tip of the diamond and fold it towards the middle

take the bottom tip and fold it so it meets in the middle

You should have two flat ends, your  shape should be a square with a triangle on the left and right

taking the bottom edge start rolling the napkin

your napkin should look like a straight line

taking one end start rolling the napkin until you have about an inch remaining, a little tail

tuck the tail into the bottom of the napkin circles

You now have a rose bud napkin
