The idea is that random acts of kindness are given without expecting anything in return. Just passing on the kindness, hoping that your recipients will do the same and forming a never-ending chain of kindness
I found this over on Crafty Chops and she is willing to make an item for her followers with nothing in return. I vow to do the same for my followers. Basically saying I appreciate you! Not sure what I will make yet but the wheels are turning.
In return you must vow to do the same act of kindness for your followers and post this on your blog.
So the first three people who comment on my blog will receive an item from me! In return you must perform your own "Pay It Forward" to three people on your blog.
