So I found a curious looking mushroom today, an Elegant mushroom. I don't have any idea how to change them into furniture, so I decided to sell it for cash.
Nook was offering 10,000 Bells for it, so I sold it to pay off my first mortgage. Was it a good choice or..?
When you find a Mushroom item, it'll make it quite clear to you that you did. You lift up the mushroom and exclaim what you've found, elegant mushrooms are for just that: selling.
