Intarsia is a simple colorwork knitting technique that uses 2 or more colors in every working row. What makes it different than stranded knitting, is that the colors are worked in 'blocks' and almost no color is worked throughout the row, only at specific parts.
That means that we have 'columns' of stitches of different colors which we work by switching between yarns. The 'trick' to achieve this, without producing holes in our work, is to twist the yarns with each other.
