Can't imagine using freezer paper to PP, but then I haven't read the tute. I use a kid's Doodle Pad, put out by Crayola Crayons, cut it from 9x12 down to 8-1/2 x 11. It is very thin, tears very easily(in fact, if your stitch length is too short it just falls off the block), and goes through your printer if you are printing the patterns off the DJ CD. Much cheaper and works just as well as Carol Doak paper. 60 sheets approximately $3.00 at Wally World.
Just want to compliment everyone on their beautiful block. I am having problems making time for even 3 blocks a week, but I am finished with my 4th block. And I'm retired!
