My middle kid wanted a hat for a Christmas party, so he went into my yarn stash and found my only skein of multi-colored Christmas sparkly yarn. The Christmas party got cancelled, so now it's a Holiday hat that will probably be worn for New Year's:
Knit in Hobby Lobby's I Love This Yarn Sparkle Art. 100, color #738 Christmas Sparkle, using US 7 needles and Melissa Leapman's Simple Hat pattern (Cables Untangled, p. 33). The yarn made a surprisingly heavy and warm hat. The pattern didn't call for a pompom, but it looked naked without one.
