Wrapped stitches can be very useful in many embellishments. A wrapped row of chain stitch can help some stitching stand out from the background when the two are the same colour. Wrapped stitches can give the line a raised appearance.
These are the main edge and line stitches used in Watermellish designs:
When wrapping stitches be sure to use the same colour and thickness yarn for a neat finish:
This close-up shows the yarn wrapped around the chain stitch:
Once you have finished your base stitch, bring the yarn up to the front (where the dot is on the left) and bring your needle up behind each chain. Be sure to go in the same direction each time for a smooth finish.
When you are finished you can sink your needle in the end of the row and weave in the end at the back of your work as normal.

I have received a request to give a more detailed explanation of the wrapped stitch technique. I hope this is helpful. 
In this example I am doing a full-thickness wrapped chain stitch, but the wrapping is the same no matter what your base stitch is.
My full thickness chain stitching:
Do your stitching, put your needle in at the end of it, and bring the needle up half a stitch back along the last stitch:
Take your needle under the last stitich:
Take your needle under the second-last stitch:
Take your needle under the third-last stitch:
And so on until you get to the start again.
Put your needle in at the end of your work:
Voila!
