I created two different shamrock patterns, one is a 4 leaf clover and the other is a 3 leaf clover. You can chain these together for a beautiful garland.
I also made a cute crocheted Leprechaun hat that can be hung as decoration. I've provided the updated links so you can get the pattern for yourself.
Check back later this week to see the Crocheted Leprechaun Hair Clip Tutorial.
