Well, now I know better and I know that it didn't look anything like a fraggle hole, but in our old house there was a tremendous hole in the baseboard, which I imagined was at about the level of the fraggle hole. For that reason, I always pictured the workshop to look like the room where our hole was located, which I now know also was wrong. Oh, by the way so no one gets confused, I am visually impaired, so I've never actually "seen" any of Fraggle Rock.
