I was reading the super crafty blog of Barbara @ http://speedycreativa.blogspot.com/
she has made a special kind of Blog Candy the PIF as follows:
1) The first 3 presons leaving a message to this post will receive a little present from me within the next 365 days...
2) In exchange, they have to do the same on their blog an initiate a PIF.
3) To get the present you have to give me their address and the link of the post where they made the PIF.
So...if you want to PIF give it a go!
