Here's another inexpensive (and quick!) Easter decorating idea. (Actually you can use it any time of the year, of course!) My local dollar store has a ton of picture frames, and on a recent shopping expedition, I picked up several, thinking I could have fun decorating them with paper and found (or purchased) objects. I went though my frame stash and pulled out a couple I thought would work, then I searched the internet for "Peter Rabbit" images and printed out a couple. You can see the two framed pictures on either side on this shelf below:
I think they turned out pretty well! You can do the same sort of thing with purchased greeting cards, papers, etc.--just put them in an inexpensive frame. It's a lot of bang for the buck--or two!
