Equilter has one they are saying is canvas, it's long and skinny. Probably would be just fine for quilting but a bit heavy or maybe a different weave than we are used to.

I have some super hero fabrics but I don't think any spiderman... but I'll take a look, box should be fairly easy to get to and I want to pull something else out of there.
Edit: I'd probably widen it out by some string/spiderweb blocks offset incorporating the colors from the top so it would be panel and then 2 or so columns on one long side by one across the top. Maybe base the top ones on a 6" block since there is so much length, and the side ones as 10-12" blocks.
