STEP-BY-STEP HOW TO KNIT FAIR ISLE
These images show what happens to the yarn that you carry over on the wrong side of the work. Work a stitch in the first colour as usual. To change colour, twist the two yarns together before working the next stitch.
Work the next stitch in the new colour as normal. When working alternating stitches of two colours, try and keep an even tension and do not pull the yarn too tight.
Change back to the original colour, not forgetting to twist the two yarns together before you work the stitch.
A completed row shows the yarn ‘floats’ carried across the back of the work. If you always keep the floats of one colour above the other colour, your work will look neater.
