I want to knit a pretty basic baby hat. Or two. I have an all purpose hat instructions where you calculate head circumfrence (what is a baby head circumfrence? It seems to me that it can vary a bit), yarn type etc. I have also looked at numerous baby hat patterns. But instructions vary greatly in the amount to CO, anywhere from 60-90 stitches. I want it to fit a newborn but have a bit of room for use up to a few months of age. I was going to make the brim ribbed with K1P1 ribbing. Anyway I started one in a worsted wt acrylic with 70 stitches and decided it looked way too small. The yarn called for size 8 needles, but my 16 inch circulars are size 7. I could cast on more and go with that, but I really want a more precise answer. I’m also considering not using the acrylic after all and making one in Sugar & Cream instead which I generally do use size 7’s on.
