there's a few ways to get prairie points into a quilt.
for me the easiest way to add prairie points is to baste a continuous prairie point strip to the front of the quilt with a 0.125 seam. i use 1 strip on each side.
the i sew the bias binding to the front of the quilt with a 0.25 seam which covers the 0.125 seam that holds the prairie points in place.
then i fold the binding over to the back and and i press the prairie points out and pin them in place over the binding and i do a decorative stitch to hold the prairie points in place and this stitch also sews down the bias binding to the back of the quilt.
since this quilt is all swirls i'll use the decorative swirl stitch.
can you do something like this for your quilt?
if not we can brain storm another way.
