Gather 6 sheets of tissue paper. Layer them on top of each other, shorter pieces on top and longer pieces on bottom. Smooth out wrinkles.
Make an accordian fold with the sheets, each fold about 1-inch. Either round the edges with scissors for a rose look or cut sharp points at the tips for a dahlia-look. Bind the folded paper with the ribbon, knotting tightly.
Gently lift one piece of tissue paper towards the binding to create petals. Repeat with the remaining paper, arranging as you see fit. Hang the rose on a wall, or, create a second rose and glue together to create a pom pom.
