Last week I was asked how I stitched the red and pink flowers at the opposite ends of the row in photo one. I promised when I stitched the next one I would demonstrate. The following photos show the stages. I am self taught and my way may be incorrect.
You can use a pencil to mark out the stitch direction or as I have done your thread. Note that the stitch I started with at the bottom was going in the wrong direction when I finished laying out the guide lines. I just laid another stitch over it as it will not show.
I have not taken the stitches all the way into the centre. I am leaving room for the next passes..
Gradually I am filling the flower moving around as I stitch so that there are no clumps of stitches.
The centre is now filled in but I am parking my thread for now in case I need to add some more stitches after the outer part has been stitched.
Note that the outer stitches in the bottom left hand corner has caused the inner stitches to gap. Pick up your parked pink thread and fill in the gap.
