What about knitting an orange pumpkin cap this weekend for Halloween? All You need is a skein of orange yarn, like Stylecraft or Bravo and a bit of some similar green yarn, and needles nr. 4. I wrote the pattern notes already down for you, some time ago, but finished them this Friday. An experienced knitter makes the cap in a few hours.
You can find the notes under projects >> colorful caps >> caps for Halloween
