Who Initiated the Fair Isle Trend
Fair Isle became very popular when the Prince of Wales (later King Edward VIII) wore Fair Isle sweater vests in 1921.

Is there a Difference between a Shetland and Fair Isle Sweater?
The name Fair Isle refers to a traditional knitting technique named after the Fair Isle, an island belonging to the Shetland Islands north of Scotland. Therefore, many vendors also call their Fair Isle sweaters Shetland sweaters.
What Does Fair Isle Knitting Technique Refer to?
The Fair Isle knitting technique refers to a pattern of different colors knit in a round. Typically, Fair Isle patterns use a color palette of about five different colors in total, and only two different colors per row. This technique is pretty easy when done with a two pointed needle that has a flexible plastic middle to hold all the meshes of the sweater.
Alternatively, five double pointed needles can be used. In this technique, four needles hold about one fourth of the meshes. The fifth serves to knit the next quarter of a round. Both ways limit how much a knitter can knit in a given color.

To avoid loose strands or that the strands catch buttons, the knitter catches the yarn not in use by the yarn in use. This technique ensures that one cannot see the strands on the outside. Typically, catching of unused strands occurs every 3-5 stitches.
This knitting technique is very suitable to create an extra layer of insulation as five colors make for a lot of catching up of strands. Consequently, a lot of air is between the various strands and thin air pockets are a great insulator. As a result, the pullover protects the wearer from body heat loss around the upper chest.
What Does Fair Isle Mean?
Unfortunately, since the 1990s, vendors and designers use the term “Fair Isle” very loosely to any stranded color knitting. Concretely speaking this means that today the name only refers only to the origin of the knitting technique. It does not identify the place of manufacture anymore, nor that the production followed the traditional technique and/or pattern.
Today these sweater can come in all kind of dyed wool as well as in various materials and colors. Of course, the wear comfort characteristics of these “fashion versions” differ from the ones made of undyed 100% wool.
Cheap mock versions of Fair Isle/Shetland sweaters have the pattern stitched onto the knit.
Note that all versions also come as vests, beanies, gloves, mittens and socks.
Is Fair Isle in Style?
A Shetland garment in the original colors, undyed wool and original pattern is an eternal classic and worth the investments. However, the fashion versions in materials and colors other than undyed wool are trends. They can quickly look dated because color trends change every year.
This is more obvious for fashion colors, while you can get away more easily with a piece in neutral colors because the annual Pantone neutral colors look quite similar. Therefore, when you love the style, but you can’t afford a high quality Shetland piece in undyed wool, go for the highest quality look-a-like in neutrals. However, be aware another material has other thermal properties. A cotton version, for instance, works fine in regions with warm, dry winters, but not in humid, cold winter climate zones.
A red-and-white version with snow-flake and/or reindeer pattern is popular as cheap, but not to ugly Christmas sweater.
What to Wear with a Fair Isle Sweater?
Fair Isle Typically, how to wear Fair Isle sweaters is to style them with wool pants, or jeans for a cozy casual winter look. When paired with a skirt it is usually a denim one or some maxi skirt for a Bohemian style look. However, the combination of a leather or hounds tooth pencil skirt with this traditional knit sweater yields an eclectic style vibe.

Wrapping Up the Characteristics of an Original Fair Isle Sweater
