i have the refurbishing one (my favorite bc alpacas), villager garden badge, happy home badge, good hostess badge, and village representative badge. That leaves me down to 18 badges (☆^ー^☆) don't really know which ones I'm missing...
I'm guessing the balloon and streetpass badges will be the hardest to get in gold. I can get lazy with the other ones, but I'm so close, I'm gonna work on it
