I am just getting started on fusible applique. A quilter I knew actually planned a project in advance to use up her accumulated leftovers. Every time she finished a fusible project, she spent an afternoon using the leftovers in her preplanned project and pitched whatever could not be used. As the blocks were finished, she would then sew them down using zig zag stitch. It was a Sunbonnet Sue design similar to that ' a year with sunbonnet sue' book. The whole thing took her maybe four years and was made entirely from leftover fusibles from other projects. Even the backgrounds were leftovers.
