I will chime in that I have used wonder under, and steam a seam lite. But I am doing a BOM with Sue Pelland and she does raw edge using misty fuse only- as mentioned above- you MUST fuse the fabric before fussy cutting the shapes, but it comes out soft as butter. I don't think I will ever go back to using a fusible with a release paper- it's so much easier and softer! There is no gumming on the needle at all either. Now what to do the whole roll of wonder under I have lol!
