They're both DIY recipes. You can find them all the time on the nooks cranny board. That's where I got both of mine.I don't have any because idk how to get them. i wouldnt mind setting up a memorial for my cat Daisy in game.
I want to use gravestones, but I have no idea how/where to fit them into my island "theme"Evershine is too much of a personal comfort island to have a full graveyard without it looking out of place, and my house in the forest is supposed to be more abandoned than haunted (despite the fake art and the character living there being associated with ghosts)
But I love and want them.
I put one in my garden but like some people here it's purely for aesthetic reasons, besides I feel like putting a memorial for a real life person in the game would be a huge mood killer every time I pass by it :/ especially since I play this game to cheer me up
