What knitting needles would you use?
 

I have made 2 hats, but I am wanting to make the curly purly pattern at the bottom for our little girl.

I will be doing the medium size. What size, kind of knitting needles would you use? I got Patons Classic Wool worsted for Christmas.

Thanks for all the advice.

Very cute pattern. A size 4-7 needle should work for you depending on whether you're a tight of loose knitter. Knit a swatch with about 25 sts cast on and knit for about 4 inches. See what needle gives you close to 4.5-5sts/inch measured over the center 18-20sts.stitches. The kind of needle depends on your preference: wood, metal, bamboo, etc. It's whatever you prefer.
