Kristi's comment reminded me of something I forgot to add to yesterday's post (I really did plan to say something about allergies).
Sweet Annie is in the ragweed family and can cause the same allergic symptoms. I don't have a problem with it (obviously) but just to be safe, I keep it away from anyplace in the house my husband spends a lot of time. :)
He is allergic to ragweed and has never shown any reactions to me just hanging it in the same room. Just to be cautious, I did stop using a sweet Annie wreath on our front door long ago. I certainly didn't want my husband or friends to enter the house sneezing!
