We didn't forget about this holiday, so meet free userheads: и
You can find them in LJ Shop. You can also find there lots of monsters, princesses and other creatures that can become funny Halloween "costumes":
A little reminder: you can buy userheads to your friends as a gift (works for free userheads too, but you can give not more than 15).
We also have Halloween gifts (one of them if free today, so send it to 20 of your friends)!
