Whenever I start thinking of bringing spring into the home and adding a charming spring décor around the place, it is always flowers (normally!) that come first on my mind!
And although the season is literally killing me with pollen all around me, (I've allergies), I would attach a crate with upside down flowers on my ceiling in an instant. It does give the place a special feel. Like being in a home of a forest nymph :)
Another great idea - and this can be done with artificial flowers so that the whole project lasts longer is to make a flower wreath / dream catcher. I am already working on some dream catchers for girls I hope would be able to show soon.
The simplest and the most effective idea is to take jars, vases, bottles, pots and buckets, spread them out through the house and put a small piece of heaven inside.
