Take the paper roll and a select a colored craft paper to cover the roll. Cut out enough craft paper to cover the entire roll on the outer side. Simply use craft glue to wrap and cover the entire roll with the craft paper.
Select a different colored craft paper and cut out small round shapes from it. Use craft glue to attach the round shapes on the paper roll covered with craft paper.
Now gather orange, white and green colored craft papers. Cut out long strips from the papers. The length of the strips would depend on your choice; but keep the width between 1-2 cm.
Take a cut out strip and apply a small amount of glue on any one side of it; Join and press the glued area with the roll, near its edge. Continue to glue the rest of the strips similarly on the same side.
You can stop attaching strips once it reaches the first strip. You can use different colored craft papers to decorate the roll for variation but for the strips use the 3 colors (orange, white and green).
