Just want to mention about the Eleanor Burns technique -- sewing a fusible to the piece, making a slit in the fusible, then turning inside out -- that it does not work well for small pieces and pieces with a lot of detail. This method works best for larger shapes with fairly smooth curves, such as medium or larger flowers, or large flower petals. I tried this method on a typical size Sunbonnet Sue block and found it didn't work well for small pieces.
