This is a super easy technique which creates a really dramatic statement!
Either follow the pattern for Cuibhrichte or work up a small swatch.
If making a swatch decide where you want to start the braid and place a marker. Place a removable stitch marked in the first stitch on the left-hand needle then (k1, p1, k1) into the stitch. Continue working the swatch as you wish. When you’re ready to work the braid knit to the marker and follow the instructions below. Make sure you have worked a number of rows that can be divided by three including the increase row. This will give a vertical braid. Cuibhrichte uses increases and decreases to create a slanted braid.
