The shawl takes about 50 g of 2/30 yarn.
Any of ColourMart’s lace weight yarns can be used, such as the 2/30 merino, 2/28, 3/36 or 4/48 cashmeres and all the blends of roughly similar weight
This could be worked in a heavier yarn for a bigger shawl. Using ColourMart 4 ply yarns and 4.5 mm needle you will need about75 g yarn, and usual ColourMart fingering yarns with 6 mm needle you will need about 125 g.
