I found this lovely frame at Dollar Tree and added some homemade art for Valentine's Day, which I posted here. Well I decided to change it up a bit for St. Patrick's Day. I added a paper flower, stamped Happy St. Patrick's Day, and then inked the edges a bit.(sorry this photo is not the greatest - it was late).
I added my art to the picture frame and voilà St. Patty's Day decor.
