Is your batting polyester?
If it is, you can't really use fusible interfacing/stabilizer because the batting won't take the ironing heat.
If it isn't, you might try this from joannes. I have done virtually a whole quilt using something like this because the fabrics were "sleazy" (not all were cottons), and it was fine.
