I can't decorate. I have a flashing gold bar that says place under dog lovers. I'm stuck?

You must have received a Marvelous decoration from the pink (5-star) box and it is ready to "place". Tap "place" to put it on your island. Make sure you have enough space on your island, such that the decoration will show a green base (not a red base). If you don't have room, place a few low-flower decorations, like paths/grass, into storage.

Tip: If you buy too many low-flower decorations, you will run out of island space. Buy some high-flower decoration (100-600 flowers/square) to save space.
