Introduction
Definition of Fair Isle knitting
Fair Isle knitting involves using two or more colors of yarn to create a pattern that alternates between colors. The pattern is created by carrying the unused yarn behind the work in “floats” of varying lengths.
History and origin of Fair Isle knitting
Fair Isle knitting has been practiced in the Shetland Islands since the 19th century, and was traditionally used to make warm and durable garments for fishermen and seafarers. Today, Fair Isle knitting is a popular knitting technique used to make everything from hats and mittens to sweaters and cardigans.

Materials needed
- Yarn
When selecting yarn for a Fair Isle sweater, it’s important to choose a yarn that is suitable for colorwork and has good stitch definition. A wool or wool-blend yarn works well for Fair Isle knitting, as it is warm and holds its shape well.
- Knitting needles
The size of your knitting needles will depend on the weight of the yarn you choose and the gauge of your swatch. Circular needles are recommended for knitting a Fair Isle sweater, as they can hold the large number of stitches required for the body of the sweater.
- Stitch markers
Stitch markers are helpful for keeping track of the beginning of rounds and for marking pattern repeats.
- Tapestry needle
A tapestry needle is used for weaving in ends and seaming the sweater together.
Choosing a Fair Isle pattern
- Selecting a pattern
When selecting a Fair Isle pattern, consider the complexity of the design and the number of colors used. It’s a good idea to start with a simple pattern if you’re new to Fair Isle knitting.
- Understanding pattern repeats
Most Fair Isle patterns have a repeating pattern that is worked across the entire sweater. Understanding the pattern repeat is important for keeping the design consistent and for adjusting the size of the sweater.
- Color choices and yarn requirements
Choosing the colors for your Fair Isle sweater is one of the most exciting parts of the process.
- Consider choosing colors that complement each other and that work well with your skin tone. Make sure to purchase enough yarn for the entire sweater, as you’ll be using multiple colors throughout.
Swatching and gauge
- Importance of swatching
Swatching is an important step in knitting a Fair Isle sweater, as it allows you to determine the correct gauge and adjust the pattern as needed.
- How to swatch for Fair Isle knitting
To swatch for Fair Isle knitting, cast on a small number of stitches using the recommended needle size and yarn weight. Work in the round, alternating between colors every few stitches to create a stranded pattern. Measure your gauge over several inches to get an accurate measurement.
- Measuring gauge
Measuring gauge is important for ensuring that your sweater fits properly. To measure gauge, count the number of stitches and rows in a 4-inch (10cm) square. Compare your gauge to the gauge listed in the pattern to determine if you need to adjust your needle size or pattern.
Cast on and beginning the sweater
- Provisional cast on
A provisional cast on is recommended for Fair Isle sweaters, as it allows for easy adjustment of the length of the sweater. Use waste yarn to cast on the required number of stitches, then switch to your working yarn and begin knitting the hem of the sweater.
- Knitting the hem
The hem of the sweater is usually worked in ribbing or garter stitch, and sets the foundation for the rest of the sweater. Make sure to knit the hem with a smaller needle size than the body of the sweater to ensure a snug fit.
Body of the sweater
- Following the pattern

Once you’ve completed the hem, it’s time to begin the body of the sweater. Follow the pattern and work the stranded colorwork pattern, making sure to carry the floats behind the work as you knit.
- Keeping tension even
Keeping an even tension is important for creating a smooth and consistent fabric. Try to keep your floats loose enough to allow for easy movement of the yarn, but not so loose that they create holes in the fabric.
- Marking pattern repeats
Use stitch markers to mark the beginning of each pattern repeat, which will help you keep track of the design and ensure consistency throughout the sweater.
Shaping the sweater
A. Decreases and increases
Most Fair Isle sweaters are shaped with decreases and increases, such as knit 2 together (K2tog) and yarn over (YO). These shaping techniques will create a tailored fit and shape the sweater to your body.
B. Following the pattern for shaping
Follow the pattern instructions for shaping the sweater, making sure to keep the stranded pattern consistent.
Sleeves
A. Provisional cast on for sleeves
Use a provisional cast on to begin the sleeves, which will allow for easy adjustment of the length and fit of the sleeves.
B. Knitting the sleeves
Knit the sleeves following the pattern, making sure to keep the stranded pattern consistent and to decrease as needed for shaping.
Finishing the sweater
A. Blocking
Blocking the sweater is an important step in finishing the garment, as it will even out the stitches and allow the sweater to hold its shape. Wet blocking is recommended for Fair Isle sweaters.
B. Seaming the sweater
Use a tapestry needle and the mattress stitch to seam the sweater together. Make sure to match up the pattern across the seams for a professional finish.
C. Adding the collar and cuffs
The collar and cuffs can be added using a variety of techniques, such as picking up stitches and knitting a ribbed collar or using an applied i-cord.
Adding finishing touches
A. Weaving in ends
Weave in any loose ends from the color changes using a tapestry needle.
B. Adding buttons or a zipper
Adding buttons or a zipper can add a finishing touch to the sweater and make it easier to wear.
Additional tips and resources
- Tips for handling multiple yarns
When working with multiple colors of yarn, try to keep the floats loose and to work with shorter lengths of yarn to avoid tangling.
- Resources for finding Fair Isle patterns
There are many resources available for finding Fair Isle patterns, including knitting books, online knitting communities, and Ravelry.
- Tips for customizing patterns to fit your measurements
If the pattern doesn’t fit your measurements, consider adjusting the number of stitches or rows in the pattern repeat, or adding or removing shaping to achieve the desired fit.
