Must be quite the secret then! In any case, I hope it stays as secret as it currently is, as I quite enjoy this glitch and would hate to see it go.Having spent 2 years reverse engineering Terraria, I'm still relatively sure that there is no bug that makes the client place an object inside another one in singleplayer, and this is the necessary first step to making the framing code apply framing to the wrong tiles.
It also shouldn't be anything special to get this working without a bast statue or campfire, as there are tens of other tiles that can change their framing dynamically, some of them may just require more math.
