binding mistake-what do I do now?

I'm back home after a blur of time in So. Fla.
Before I left home I was trying to attach a binding to a quilt by machine. This has never been a problem for me before, but this time the quilt is backed with polar fleece. I used a decorative stitch, which I've done before, but the machine is not feeding the quilt through, the feed dogs don't seem to be catching. I have the walking foot on. In several places the stitches have made a bird's nest, and it is generally bad looking. I'm about 1/2 way through.
Any suggestions? Do I just soldier on, and try to pull it from the back, or what?
I'm up for suggestions.
