Sure why not. For the month of Decemeber, there are three twists. Two of them are not big twists, just things to add along, and the third twist itself, does not have to be big or expensive either-you can have many different ways in working with this twist.
I will announce one of the twists now, and once all the letters have been received, I will annouce the rest of the month of December.
So one of the twists is......to send your pen pal a holiday recipe!
