Sue's sample as shown in my first photo, was quilted over wool and doesn't include any trapunto. Using large feathers with smaller filler stitches between them, makes the feathers pop when using wool.
Sue was a lovely teacher, very knowledgeable and I feel like I finally "got it" when quilting feathers without marking. She also had lots of suggestions for troubleshooting problems. We practiced stitching the feathers on paper at first and now I need to practiced so I develop muscle memory and confidence. I can really recommend the class.
