first cut 6 pieces of fabrics 6"diameter and 1 piece of fabric 4" diameter.
once you have all the pieces , fold the bigger pieces (which will become the flower petals) into half and then half again like in the picture below.
you will be having all 6 pieces folded into quarters.
next sew at the end of it with running stitches and connect all six pieces together. you could do it by hand or machine but i prefer sewing it by hand as i can adjust the distance between the stitches.
as for the smaller pieces (which will become the center of the flower) i stuffed it with rags from fabric or you could stuff it with cotton fiber and stitch it closed.
thats it, very easy and simple ! if you have any questions , drop me a line :)
