It took me a couple of tries to get these right. The first mitten (post and pic last week) was far too small. I was able to take the hem out, lop it off, pick up the sts and then knit a new cuff. It's now the right size for my 3 year old Spidey-obsessed grandson.
These are very specifically sized, for a 3-4 year old child. If you want to knit larger child-size mittens, I suggest adding a couple of sts to the vertical borders, using size 3 needles, adding cuff length, and working a few more rounds of web before the decreases. You will also need to set 1 or 2 more sts aside for the thumb, and pick up that many more when you knit the thumb(the extra sts can be part of the side border). If you want to knit an adult size pair, I would try worsted weight yarn and size 4-5 needles and this pattern (you may have to adjust the length, but you might not).
As mentioned, these mittens were inspired by Pumpkinmama's We Call Him Spidey Hat, and she gave me permission to use her chart. Thanks so much! My grandson will be delighted!
