Yardage: (830, 1250, 2490) meter, yardage on this type of project can vary, this is only a guide, an average of how much my tester and I used, you might need more or less than this, it depends on your personal knitting style.
Yarn: Heavy DK - light worsted weight, I used Abuelita Yarns Merino 4ply (250 meter/100 gram, 100% wool) for the undyed one and Excelana Luxury DK 1(25 meter/50 gram, 100% wool) for the pink.
Gauge: 18 stitches/10 cm and 31.5 rows/10 cm in garter stitch on washed fabric worked back and forth.
Needles: 4.5 mm or size that gives you the gauge called for on washed fabric and a cable needle or dpn in same size or smaller. A circular needle will be the most ergonomic way to knit this blanket. I recommend using a 80 cm for the two smaller sizes and a 100 cm for the largest size.
Sizes: Crib size, Lapgan/child size, large blanket size. Size can be adjusted with included adjustment guide.

The instructions are both written and charted so you can choose the way you prefer.
