Can you post an item on Pay it Forward that you will give someone if they want to pay the postage? I am not familiar how to do this.

Absolutely! Go for it.

What section do I post it in.. Is there a special section? Sorry I ask so many questions. I found a pay it forward section once, I thought, but can't find it now.

Here's the PIF thread: http://www.quiltingboard.com/t-45265-29.htm

You could also make a new post in the classifieds section.

you might have better luck posting in the clasifieds.
