The Flower Stitching Foot has been around for ages, however within the last year or so Singer has started bundling it with their new machine foot packages.  This foot will work on most low shank zigzag machines.  Not long after that, I actually got one.
Notice the – sign on the left and the + sign on the right.

The large screw in the front of this pic is how to adjust the size of the flowers.   Loosen screw and pull the center line to the left or – sign for smaller motifs, set line in the center for mid sized motifs and set line to the right or + sign for the largest motifs.
It’s quite a fascinating foot on the large side with unlimited potential.  It didn’t come with many directions or a chart to help with stitch selections, so I will detail the stitches I tested out.  The stitching patterns kind of remind me of the old “Spirograph” set I played with endlessly as a child, that I STILL HAVE!!
I decided to set up the Flower Stitching foot on my Singer Quantum L-500.   I lowered the feed dogs, set  the stitch to a wide zigzag and then pulled the thread up from the bobbin.  Everything seemed fine until I went to sew.    The machine sort of started to act “possessed” for the lack of a better description.  It would stitch a few stitches and then it would stitch erratically on it’s own.  Weird…..It was stitching WITHOUT me pressing the foot pedal or the start/stop button!!  The only way I could get it to stop was to shut the machine OFF.  Well after repeating the whole process over again and then again, I took the Flower Stitching Foot off to see if the machine would stitch in a regular setting again.  It worked just fine.  phew……
 
I was disappointed at this point, but just wanted to see what this foot would do so I went and set it up on the Singer Quantum Stylist 9960. Once again I installed the foot, lowered the feed dogs, selected a wide zigzag and pulled up the thread from the bobbin. I held my breath and hit the gas. It stitched beautifully!! So I played and played with different stitches and had a fun time. So now I knew it wasn’t the foot, but what was the problem??
 
I went back to the L-500 for further inspection. I reinstalled the foot yet again and followed all the same set up instructions. This time I noticed that when I engaged the presser foot lever, the foot didn’t go down every time. I found that the bar that’s supposed to ride over the needle bar was interfering with the dual feed. This foot WILL NOT work on the L-500. Part of the mystery was solved!! However, I still don’t know why it was stitching on it’s own though……..hummm……

Now back to the 9960 for some more testing.  This foot has a HUGE amount of potential.  Almost unlimited combinations can be used to create all kinds of pretty flowers.  Not to mention all the different thread possibilities and combinations!!  The one thing that I want you to be aware of is that not every stitch will end perfectly where the stitch starts.  In other words, sometimes it doesn’t make a perfect flower.  So if you’re looking for a perfectly completed flower every time with every stitch it’s not going to happen easily.  It probably can happen if you do lots of testing of different stitches to find the right combinations, but I wanted you to be aware of this minor imperfection.  I wasn’t interested in that anyway.  I just wanted to explore this foot and work within it’s parameters.
Close up of the foot attached to the 9960.  Notice how the bar on the foot rides right on top of the needle bar with no obstructions like with the L-500.
Now on to what I did with it.  I used a black denim with fusible interfacing for my testing.  I tested many stitches to see which ones made the best looking flowers.  I was pleasantly surprised in what I found.  Quite a few of the factory set stitches worked pretty close to perfectly and those that didn’t just needed to be stitched around another time or two.  THIS FLOWER FOOT IS A WINNER!!!
Here I’ve detailed a few stitches done on the Singer Quantum Stylist 9960  in different sizes for you to understand the potential of this foot.
Stitch #29 S stitched 1x around, M&L stitched 3x around
Stitch #95 SML stitched around 1x
Stitch # 62 SML  stitched 2x’s around
Stitch #12 SML stitched around 1x
Stitch #14 SML stitched around 1x
Stitch #9 SML stitched around 1x
I hope you can see all the wonderful effects that can be achieved with this foot.  Imagine mixing the different stitches in contrasting colors!!  I think my wheels are spinning, what about yours!!
