I thought I'd given up on pp-ing but maybe I'll try this method too. I WANT to like pp-ing but just never have yet.
Just FYI, I found this about freezer paper shrinking a bit on another website:
"On HGTV's Simply Quilts website, I found the episode that Sharon Schamber appeared in (QLT-1004). It does say that freezer paper shrinks in the WIDTH, but it doesn't say how much. It also says to pre-shrink it with starch and an iron."
