I took a dress pattern and added the prairie points. Cut out squares (3 1/2"). I used different black and white prints and solid white between each one of prints.
To make a prairie point bunting: Fold one square in half, diagonally, wrong sides together. Fold that triangle in two, lining up the folded edges. Hold in shape with pin or clip, until you have made enough to put around the hem. It took 21 for my size 3 dress. Press.
Place the points one on top of one another, overlapping by half with points down. Stitch across the raw edge top to hold in place. Place the bunting on the hem with right sides together.
Place bias binding on top of the bunting points, wrong side facing up.
Stitch in the first fold of the bias binding. Turn the bias binding completely to the inside of the dress. Refold bias and sew from folded edge. This can be top stitched or by hand to hide the stitches. Press.
