first i took some white tissue paper and glued 3 sheets together to make it stronger and used water colour paints to paint it lilac, then gently i painted a sheet light cream.
once dry i cut the lilac tissue out in individual petals and put to one side, then i cut the cream piece in to a 3 petal shape, like below
then i painted some lines on and a yellow centre and glued them together.
i got some thin wire and wrapped it with tissue and painted it green and glued it to the back of the flower.
if you don’t want to paint your own i have made a printable for you at the bottom of the post
