This stitch is nearly invisible and it’s used to finish a work or to close a line.
Working with slip stitch you get a very close fabric, so you’d better use a bigger hook than the one suggested on the yarn.
To realize it:
-Slip the hook in the second chain away from the hook, passing under two of the three yarn-arms that compose each chain; then wrap the yarn over the hook from back to front, pulling it directly through the loop on the hook.
-repeat these movements until you reach the end of the line, then turn your work, chain one and repeat.
