I made this super simple St. Patrick's Day shamrock garland last week and had to share. I began with cute patterned cardstock. I found a shamrock stencil online; then folded the cardstock and traced the shamrock onto it and cut it out, making sure not to cut the top so that the shamrock would have a front and back/open (see photo below). Then I ran a piece of ribbon between the folded shamrocks. I slid a piece of double-sided tape between the two sides of the shamrocks so they wouldn't slip off the ribbon. Now, it hangs festively on our front door.
