Horrible Quilts

Those polar bears have really done it this time. I caught one of the cubs, lounging on the human's pillow and whispering into her ear as she was snoozing, on how she could win a prize in the quilt show the next time it comes around. And of course, this will require more fabric purchases. They already have a website picked out, where these fabrics can be obtained, too. And they're trying to tell her a mini-quilt would work best, so there will be loads of fabric left over for them. Does anyone know how I can block such a dangerous website?
