I like the idea of stitching the white with Rainbow Gallery Wisper Thread, which looks like hair, in white or antique white. The blue curly-cues in the beard would look good in the same brand of floss, but in pearl gray. This site does not stock this thread, but it is available at 123stitch.com
You need a stiff and a soft toothbrush to brush the floss when you done. Kids enjoy petting this floss. You could do the hair and Santa's coat trim in this same Wisper white thread, but I would stitch the snowman's bottom in regular white floss. The kit will not tell you that you can use Wisper for human hair and beard and for animal fur because it comes in several colors.
