Hello all!
I have made several VB "knockoff" bags (for myself, not for nefarious purposes) in the past using pre-quilted fabric before I started quilting and of course realized it would be relatively easy to "pre-quilt" my own fabric for these projects and I wouldn't be limited to the prints they carry. I have yet to try this though. I guess my questions is- is it worth is to purchase pre-quilted if I find a print I like. It varies between $10-20 per yard. I can do math on it pretty easily, but how about the time involved? Thoughts? Has anyone done anything like this?

Thanks all!
