between Trash to Treasure and Garden Junk?
The location. One is on the Garden Forums side of GardenWeb, the other on That Home Site, or the Home Forums side.
Contents-wise, I think Trash to Treasure deals with things made for anywhere--garden or inside the home. Garden Junk deals primarily with things made specifically to place outdoors in gardens.
Ditto! I have not visited in awhile, and I was just thinking many people who are posting here really would be happier over in the garden sites. Not that they are wrong here, they would jist get a lot more hits, and if they did a search they would find many of these current questions have been done to death over there.
