Thanks, John.
We'd already checked the Hasbro site and it proved accurate. The blue-green Playdoh was (we were told) dropped onto the sisal rug, danced on then rolled up 3-4 years ago and forgotten. We laid it out with the loops sort-of opened up and scrubbed with a toothbrush and little metal tool to mechanically dislodge the particles of dry Playdoh. After vacuuming, one really has to know where to look and then get on hands and knees to see some of it down next to the backing below the loops. Darn near a miracle.
