Crochet St. Patrick Shamrock Coasters

St. Patrick is just 10 days away and I have just crocheted a pair Shamrock Coasters to go with my beers during the festive celebration. Bring on the beer and be an Iris for a day! Click the “Blue Bar” above to make yours today with the pattern and tutorial shared on the next page. 

“Three-leaf clover of a shamrock is also said to stand for faith, hope, and love.”

Similar to the Valentine’s Heart Coasters, these Crochet Shamrock Coasters were made from colored jute twines. However, you can always substitute it with normal yarn, preferably sport-weight yarn. Crocheted by using a 2.5mm hook, the size of the coaster is 3.75″ x 3.75″. Read more at the pattern and tutorial page.

If you need a four-leaf clover design to symbolize GOOD LUCK, you may easily tweak the Shamrock Pattern to a 4-Leaf Clover by replacing the stem area with another leaf petals.

More Details on how to crochet the St Patrick Shamrock Coasters

Choose your favorite yarn in yellow and green color to crochet. I used 2-ply jute twine, it’s thickness is roughly 1/16″. You may use sport-weight yarn or equivalent thickness.
The corresponding hook size for this yarn is 2.5mm. With these yarn weight and hook size, my coaster came out to be 3.75″ square. The coaster’s size will vary with the different weight of yarn and its corresponding crochet hook. Choose something similar so that the coaster size won’t go wild.

Pic A. Insert the hook into the “bar” of a chain stitch to make the first single crochet stitch. The “bar” of the chain stitch is the vertical line at the bottom of a chain stitch, you will find it when you turn the chain bottom side up.

The reason for crocheting through the “bar” of a chain stitch, it will make the first and the last edges look identical after the crochet piece is completed.
Follow the crochet pattern to make the first 3 rows of single crochet with Khaki color yarn.

Pic B. The colorwork Begins at row 4 where Green yarn is added to create the shamrock pattern.
Follow the pattern to work on stitches in Yellow yarn until the last yarn over, pull through the loops with the Green yarn.

Still at Row 4, Since the Yellow yarn is still required after working on the Green stitch, we need to carry it along and hide it in the Green stitches.

Pic C. Just before the yarn-over of the new color at the last stitch of old color during the color change, always bring the new color under the old color yarn and away from the working piece as shown in the picture, vice versa, bring the old color over the new color and nearer to the working piece. In this case, the process is crossing the Yellow yarn under the Green yarn, with the Yellow yarn further away and the Green yarn nearer to the working piece, then yarn-over with the Yellow yarn.

Pic D. According to the pattern of row 4, the Green yarn is still needed after the 6 yellow stitches at the center, thus, carry it along and hide it in the Yellow stitches.

Pic E. Continue to crochet with Yellow yarn until the pattern calls for color change.
Similar to Pic C, bring old color (Yellow) nearer to the working piece and new color (Green) behind it, yarn-over with the new color (Green). And again, since we need to switch back to Yellow yarn after that, so carry the khaki yarn along and hide it in the Green stitches. 

Pic F, after the making the last stitch of Green, the Green yarn is no longer needed in row 4, cross the green yarn over the yellow and bring it to the front of the working piece before making the first Yellow stitch. Finish off row 4 with Yellow yarn.

Pic G. Work on Row 5 with a similar technique of color-change and yarn-carry-along that you have done in row 4. However, take note that you will need to carry the Green yarn to the next 2 stitches as shown in the picture. The reason being that we need to work on Green stitches at the 4th stitch on row 6, so carry the yarn to where it needed to be used for the next row.

Pic H. Continue to work until you reach Row 9. When you reach the Green stitch of the previous row where the green yarn is located, and you still have 2 more stitches on Yellow before working on the Green yarn. Read the next instruction.

Pic I. Carry the Green yarn in the 2 Yellow stitches then cross the yarns for color change followed by crochet 2 Green stitches. Remember to carry along the Yellow in the Green stitches for the next color change. Follow the crochet pattern, perform the color change and carry-along as before.

Pic J. At Row 10, carry the Green yarn in the Yellow stitches until it is needed for color change.

Pic K. Cross to change color as mentioned before.

Pic L. Still at Row 10, again, carry the Green yarn to the next 5 stitches for it to standby for Row 11.

Pic M. The carry-along of Green Yarn happen again at the last few stitches of Row 11.

Follow the pattern to complete St. Patrick Shamrock Coaster.

Hide the yarn ends and block it to a square.

Bring on the beer and be an Iris for a day! Happy St. Patrick Day!
