Notes:
This flower measures 8-10 cm in diameter.
It is worked by creating the base first and then working the flower petals into the stitches of the base.
This pattern is for a four-layer petal motif, however, it is possible to create a three-layer petal motif by omitting Round 4 of the petals. You will need a larger button to fill the centre space.
