You will need:
-- an afternoon, well maybe a couple of them
--100 to 200 grams of yarn, depending on the size you choose.
Size 1: 70-100gr/152-218yd, Size 2: 130-160gr/283-348yd, Size 3: 170-200gr/370-436yd.
—16 inch circular needles that are the appropriate size for your yarn and knitting style. Read your yarn label suggestion for needle size, knit a swatch, do the math and see if you are getting the suggested gauge, if not go up or down a needle size.
I used size 6 for 5 st/in, size 8 for 4 st/in, size 9 for 3 st/in. I am unabashedly a loose knitter and will do it, knitting of course, just about anywhere, anytime, with anybody ...
