Here are the parts you need:
2 inch squares: 3 green and 1 white
3/4 inch squares: 6 white
1 x 2.5 inch strips: 2 white
1 x 3.5 inch strips: 2 white
4 inch square: 1 white (backing)
4 inch square: batting
Let's get started:
Place a small white square in the corner of a green square. Stitch across the diagonal. It's so tiny that I didn't feel I needed to mark it. Repeat so that all three green squares have white squares on three of the corners. Flip and press to the corners. Clip off excess on the corners if you wish.
Stitch the 2 inch blocks together into a four-patch as shown. Layer the batting and backing pieces. Using a quilt-as-you-go method, lay the folded back four-patch with the center edge in the center of the batting and stitch through all layers. Flip open.
Add white border strips by stitching through all layers and flipping open. Finger press as you go. Top-stitch the borders about 1/2 inch from the inside edge, using your machine foot as a guide. Trim outside your top-stitching with a pinking shears. With the remaining 6 inches of ribbon, add a loop at the top corner to hang your ornament.
But, teeny tiny isn't always what we need.
The same shamrock block can be made to finish at 3 inches, which makes a nice size for lots of small projects.
For this table topper which finished at about 12 inches square I made two 3-inch (finished) shamrock blocks and paired them with two 4-patch blocks made from 2-inch squares.
The shamrock blocks each are made with:
1 inch squares: 6 white
The borders are each cut at 2 inches wide.
Can't wait to quilt this up!
