oooooo noo, it's not scary. Most of what I do is applique. I can't make 2 pieced blocks come out the same size!!
I don't use any kind of fusible stuff. I just use a plain ol' kids glue stick. You can move your pieces around for a good while until they are stuck good. It washes out completely and doesn't have the stiffness of that fusible stuff.
Fat Cat has a bunch of applique patterns
