i must confess ... i'm confused.
the fusible products are used to "glue" the applique pieces to each other and/or the background. the first step fuses the fusible to the back of the fabrics being used to make the applique pieces. if you don't take the second step of peeling away the paper on the back, it won't stick to the background/other pieces after you've cut them out.
how did you get the applique pieces to stick to the background before you quilted it?
