It's okay to just throw it away or stuff it in the back of the closet.
I just threw away two yards of black fabric, the fusible web fused to the back of the fabric and a $10 pattern. I took a class on an interesting technique and because I don't have a quilt shop handy I bought black fabric from Walmart. The technique involved freezer paper and it absolutely would not stick to that fabric and after trying to stick it to that fabric it wouldn't stick to any thing else either.
I considered attempting to salvage the fabric and fusible some way but I decided my time is too valuable to fight with cheap, crappy fabric.
The moral, if you really hate it, toss it and start over.
