Berry stitch but is also known as double lazy daisy stitch or double detached chain stitch. It can be worked on any type of fabric and is easy stitch to do and learn.
You can work it as an isolated stitch, in patterns or substitute it in places where you might want a fatter detached chain stitch. It can be worked close together in a line, or massed.
Since this stitch is made up of two detached chain stitches you need to know how to work detached chain.
A twisted thread, such as pearl or soft cotton, is ideal as it will help hold the shape.
Insert the needle back just above the top of the first chain stitch.
Take the needle through the fabric behind the first chain stitch bringing the point of the needle out a short space below.
With the thread wrapped under the needle point pull the needle through the fabric to make the second chain stitch.
The completed stitch looks like a fat chain stitch.
As your pattern dictates you can increase or decrease the number of petals in the flower.
You can also work this stitch in two steps the first round of chain stitches being in one weight of thread and the second being in a heavier or slightly textured thread.
You can also substitute the first chain with an oyster stitch to produce some really interesting results as the middle is more textured if you use an oyster stitch.
Berry stitch worked in two steps in silk ribbon can also be very effective.
