I,m so glad to read this post because I did this last week and will never try to free motion
again using two layers again. I did mostly straight lines with a walking foot, which was no
problem. Then I tried to do feathers on the borders and should have stopped when I saw
how they looked, (awful). When I finished, I was so disappointed about the way it looked.
I knew that since this was a gift, I had to rip it out. It took me ten hours to do it and vowed
NEVER to try this again on two layers. I guess the saying "live and learn" very much applies
in this situation.
Oh and I used warm and natural batting.
