Chevron chain stitch is a really great stitch to come to grips with. I have seen it called zig-zag stitch in other places which I suppose does fit when you think of how the beads are strung together but quite honestly, its not the name that counts but what the stitch actually looks like that matters!
The basics are quite simple and you can continue in rows and thereby cover quite a lot of space more quickly than you would with say, a loom woven piece or a one done in peyote stitch (you also use fewer beads…always a good thing if you think the colours you’ve got aren’t going to last the distance!)
I recently wanted to cover the outside of a miniature set of wooden drawers I had made because you could see loads of
imperfections in the wood but I knew the amount of beads I had just wouldn’t be enough if I used brick, peyote or a loom stitch - hence the chevron chain stitch came to the rescue! You can see a section of it here. It also makes really pretty pieces of jewellery that have a lovely delicate look to them - imagine putting a clasp onto this piece and immediately you’ve got a stunning cuff bracelet.
Anyway - I’m going off the point - here are the basics:
(N.B. The beads in the drawings below are pulled apart so the direction of the thread can be more easily seen between them.)
1.Thread a stop bead onto your thread and leave about a 12- 15cm tail (around six to eight inches) Now thread on ten beads and take the needle back up through the first of the ten beads and pull tight so a loop of beads is made.

2.Now string on six more beads and take your needle through the fourth bead from the starting bead on your loop. Again take up any slack on the thread.

3. The rest of the row is basically repeating this last step remembering to take the thread back through the fourth bead of the last six beads you added until you have the desired length of stitching.

4. When you have the length you want, take the needle back through last beads so the thread exits at the bottom bead (the one high lighted in pink)

Add ten more beads. Take your needle back through the first bead and pull the thread through in order to make a loop. Now take the needle back through the same three beads of the last row (again highlighted in pink).

Continue to stitch the row as before but use the previous row of beads as the top line in the next row.
When you reach the end, weave the thread through the beads as you did at the last turn and stitch row 3.
Continue in this way until you reach your project’s length.
As I said at the beginning, these instructions are only the basics -there are lots of variations to be made just by putting different numbers (and sizes)of beads on the outside edges.
Chevron chain can be made 3-D as well so you can start to build 3 dimensional figures - just remember to use the right sort of thread and keep the tension suitably tight!
