Fair Isle Knitting
This term is used for a pattern where two colours are used in the same row of knitting and a colour changes every few stitches.
It is usually used in stockinette stitch and you carry the yarn not being used on the wrong side of work throughout the whole pattern.
The colour yarn used most is held in right hand and the second colour is held in the left hand. If yarn is carried more than three stitches,
catch the carried yarn so you won't have long loops on the back.
Insert right needle in usual manner but before picking up yarn to work this stitch, slip right hand needle under the carried yarn,
work stitch in usual manner, dropping carried yarn as stitch is completed. Work next stitch in usual manner. Repeat from across.
