The pattern calls for the mittens to be knitted on double pointed knitting needles and although I can knit that way, I don't really like to. Just recently a friend told me about the magic loop, a method of knitting using a circular needle as opposed to 4 or 5 double pointed needles. This method is a lot easier (so easy, even my 13 year old has picked it up with no trouble) and I would highly recommend anyone who knits to learn it. I learnt from a video which you can find here.
I'm not sure what the yarn specified in the pattern is like, but I wanted to use 8 ply acrylic. With my choice of yarn, I had to change to 4mm needles as opposed to 4.5mm as stated in the pattern to get the mittens a nice size for my daughter's hands.
