Please note that the original yarn used is Drops Air and the other mentioned i.e. Lana Grossa Brigitte No. 2 is an alternative, so you need to swatch the substitute yarn first before starting the pattern.

Also the yarn will increase from 5 skeins to approximately 6 skeins (for the M/L) and 8 skeins (L/XL) depending on what size you are going to knit
