Are any Wdi Easter pin for 2018?
I don't think there was. Even DSF/DSSH didn't have an Easter set or pins related to spring released.
I think that their "spring" release was supposed to be the flowers - but agree that normally they have something that's specifically labeled with the year.
Yes, the DSF flower release was meant to be the Spring/Easter pin set this year. They always do holiday releases (monthly releases, not surprise) a few weeks before the actual holiday.
