The clue to the bunny's location will be somewhere on the home page of the quilt shop. But this is only if they're nice enough to give one. Most do, some easier than others. My advice is if you get lost or confused always go back to the home page and re-read or look for the clue. The newsletter sign-up page is probably the most common place to find the bunny.
Remember, when all else fails, screw the bunny and shop!
