This series can be found on the Pfaff website at:
http://www.pfaffusa.com
Choose the link on the left side of the page called Projects, Designs, and More! Then chose the sublink called Sewing Projects. Under that link is the America Quilts Creatively Projects.
These are a little unweildy to work with but they are pdf formats and worth the digging. For some reason, this is one of greatest irritants with Pfaff. I love my Pfaff machine and would never trade it, but sometimes, their website leaves something to be desired.
