some hints about cherry blossom recipes: -they do not come in egg balloons/bottles -Isabelle will give you one during announcements if there is no other news (new neighbors, etc) -i found it easier to find more once I finished collecting all the egg recipes (fewer egg balloons)
I have only seen it once, but I've seen others say they get it multiple days. cherry blossom stuff doesn't overlap with eggs. egg recipes come from egg-patterned things. cherry blossom is from normal balloons/bottles.
