Using 4mm circular needle pick up 100 stitches at approximately 1.5 cm intervals. There is no need to be precise about the gaps between the stitches when working with this yarn, as this will add a more natural look to the boa. Work on these 100 stitches using about 5cm of yarn between stitches and continue until ball is completed, allowing sufficient yarn to cast off (this should be approximately 5 rows).
