My filter somehow cracked....
....while my camera was in a case.
Now I can't get the filter off. Any homespun recommendations? It is on my 24-70 and I am about to go out to shoot Cherry Blossoms.

Good luck.

A local camera shop will often have the correct filter wrench in their service department or for sale.

Not that it does you any good right now, filter wrenches are cheap.
That's always good to keep in mind. I am pretty sure it has to do with whatever happened to the filter because I no longer tighten my filters very much.

saw it off. Or get someone with a stronger grip.
Never over tighten a circular polarizer. Rubber bands around the non-spinning part might work.

This is the most time consuming and risky approach. It should only be used when everything else has failed.
1, Take the lens off the camera.
2, Tape up the body with masking tape. This stops dust getting in.
3, Tap at the edges of the glass (not the center) until broken. Using a glass cutter first to score the edges helps this.
4, Remove glass by pulling the parts outwards.
5, Pack the exposed glass lens with cotton pads or balls. Anything soft will do. You are wanting to stop metal filing getting in.
6, Using a fine, metal hacksaw cut into the filter metal. Make sure you don't cut into the lens! You should aim to make at least 8 evenly spaced cuts. This helps the filter flex and bend.
7, Using clamps, twist the filter until it pops out.
8, Remove all dust using a blower (not compressed air) and remove the tape.
Once the glass was gone, I still had to remove the filter ring, which was dented so far out of shape it was impossible to unscrew. In this case I had to cut through the filter ring with some metal cutters, and then use needle nose pliers to bend it inwards until eventually it came free.
It was a nerve wracking couple of hours, but the lens still works perfectly.
