The top of this hat is MESMERIZING!!!!! This is the Twistmas by Espace Tricot We knit up this shop sample with a new yarn in the shop called Noelle . It's fluffy and sparkly...two things that make for a VERY fun hat!! I should have gone up a needle size, this hat fits me and the fake head...but it could be a slight bit bigger and I was just under on my gauge. I only needed one ball for this hat, but if your gauge was larger than indicated on the pattern, you may need 2 balls (these are 50g balls, not 100g!) We only have one color in stock right now, but the rest of the colors should be arriving soon!! A little more information about the yarn.... Noelle blends luxurious baby alpaca and merino wool with polyester and nylon to create a shimmering, ethereal yarn perfect for cool weather. This yarn features a hollow core, making it exceptionally lightweight and lofty. Noelle has a soft haze, yet retains lovely stitch definition. Subtle color shifts give this yarn an additional element ...
