small polystyrene balls
green, yellow, pink crepe paper
take the polystyrene ball and dig out the centre with some scissors to make a hole.
cut a long strip of green crepe paper and ruffle it and glue it into the hole.
now cut a long strip of yellow crepe paper and glue it on ruffling it around to hide the edge of the polystyrene.
cut the pink crepe paper in to petal shapes and glue them on over lapping each one, and mould it around the ball to create the shape. keep adding the petals until you are happy with the size. for one of the ranunculus i added some extra darker petals on the outer layer.
if you want them to have stems then glue them on with a glue gun, i used real stems that i dried out.
heres my inspiration
