Thank you, but it wasn’t hard. What’s a hood? A rectangle that’s folded and seamed at the top. When I knew my gauge with the yarn and needles it was a simple arithmetic problem that even I can do to figure out the cast on which would form the top edge which was to be seamed after the piece was folded. A few increases in the middle to give it just a little shape and the rest was mindless rows of stockinette with garter stitch borders. When I had the hood part just about long enough (I tried it on) I switched to all knits, all the time for a garter border across the bottom so the thing didn’t roll up on her. I bound off the center stitches, attached a new ball of yarn on one side and knit, knit, knit, knit until the first ball of yarn ran out.
I did use part of a 2nd ball but by making the scarf part shorter and I could just about squeeze one out a ball. I think it would be more of a neck warmer hoodie, what would we call that? A newdie?
