5 - 50 gram balls per gradient pack = 250 grams. After using 1st 5 balls, blanket measures 58” wide x 12” tall. I purchased 5 gradient packs and plan to use all 5 for this blanket. My est. finished size will be 58” wide x 60” long. If I can find more yarn (after we come out of quarantine), I might add an extra 12” to the length.
