yep, I used Nookazon to get them all.Oooh Festivale is fun! Looking forward to it. I'll probably end up using Nookazon, too, for furniture in the colors I want. Glad to hear it worked well for you.
I could also use it to get the wild paintings, but I've been lazy.
also I just looked up Festivale, since it's been in previous games, and looks like if they're doing it in this game, it will be next month.
