My grandma used to knit me a pair of mittens every year for Christmas and I loved them all. After she died, I received all of her knitting needles and yarn, and greatly wished that I had asked her to teach me some basic knitting skills while she was still able - I guess I was too young to even think of it. Finally I decided I was going to take matters into my own hands and teach myself - wow, was it ever hard! Being a leftie, learning everything right-handed made things very frustrating for a while, but I think I have figured out enough to move on from the rectangles I have been making.
Anyway, I found a pattern for mittens that seemed fairly straightforward, and I've made it through the cuff and the next few rows with no hitches, but I seem to be stuck and was hoping somebody would be able to set me straight.
The pattern is here: http://www.freevintageknitting.com/mittens/104-mittens-pattern.html
I'm working on the pair for 10-year olds, with 38 stitches cast on.
When it comes to the thumb increases, the first increase says to knit 18, inc. 1 st, k 1, inc. 1 st, k 17 sts.
But if I have 38 stitches, and am adding 2, shouldn't that add up to 40? I can only see 38 accounted for in those instructions. Am I reading this wrong? Any clarification would be awesome! Thank you!
