I have used a fusible knit interfacing on my dress neck facing....pattern V8612   I have sewn the neckline front already but it seem like it needs a little more body....its a little soft.   Can I fuse another layer of interfacing over it, using the same thing or maybe one with a bit more body?    Would I place it over my stitching line or just below it....I have not yet trimmed or under stitched the lining.

Thanks for any help!
