There are many other panels available, but they include other wildlife critters - deer, moose, turkeys, foxes.
I didn't come across that particular fabric, but did find these pillow panels - the squares would be a bit larger than the ones in the eBay quilt.
These were bears only.

Have you tried Joann's or Walmart?
I'd think in your neck of the woods that they would have something for you there.
