My gauge is a little looser than the pattern and I wanted this jumper to only have a couple of inches of ease (to fit 40”), so although I cast on size M I increased to the size XS stitch count. I also made the sleeves a lot less baggy, as usual. I used exactly two 100g skeins of Nateby 4ply, and about 150g of Brimham Boucle (must weigh it).
