Free St. Patrick’s Day Crochet Shamrock Pattern

Make yourself a little lucky charm with this cute shamrock brooch!


With St. Patrick’s day on the 17th March, we thought we’d share our lucky little shamrock pattern from issue 41. The pattern designed by our editor Sara Huntington shows the shamrock used as a brooch, but we think it would fair equally well as a hat pin or appliqué patch. However you wear it, we hope it brings you all the luck of the Irish.

This straightforward leafy motif can be hooked up in three different sizes using the same pattern. How can this be? Is it some kind of sorcery? Nope, all you need to do is adjust your crochet hook size as suggested and double up the yarn where necessary. Each cheerful little decoration is quick to make, so grab a bright green DK yarn from your stash and start stitching. You’ll find a light blocking of your finished motifs will help to define that instantly recognisable shamrock shape.
