Welcome to Sunday Stitch School's lesson of the week. Today we are playing it safe with a stitch that many learned already in nursery school, Whipped Running Stitch.
It can be found in almost any basic Stitch guide. In several books it is also known as Cordonnet Stitch. Do you remember that name from

In Swedish it goes under the names of Snodda Förstygn or Förstyng med Kastsöm.
In French it is called Point avant Surjeté.
Obviously you start with a line of Running Stitches, then whip them with a thread of contrasting colour or texture:

Easier than easy!
On my Aida sampler I used a dull purple and pistachio green perle 8.
Homework:

Whip them using a collection of fancy threads (from Oliver Twist's orange set) and chenille (from Art Fiber Endo of Kyoto).
