Cut a 10cm length of yarn, it’s sometimes useful to use a different colour to the one you are working in, so you can see it clearly when your knitting.

Fold the yarn in half and tie it in a knot, leaving a loop a bit bigger than the circumference of your needle.

Work to the place you want to add your yarn marker, then slip it onto your right needle.

Continue knitting until the end of your row.

When you reach your yarn marker on the next row, simply slip the yarn marker from the left needle to the right needle. Make sure you don’t knit your yarn marker!

Continue knitting in this way, slipping the yarn marker on every row.
