So I totally forgot about Free Pattern Friday last week! This week let's celebrate March 1 with a St. Patrick's Day theme! Our free pattern today comes from my friend Michelle over at The Perfect Knot. I actually had the opportunity to test the pattern for her Lucky Shamrocks. This pattern is so versatile because you can use thread or any size yarn to make them and you get the option of a 3-leaf shamrock or a 4-leaf clover.
