At our monthly quilting group this week, one of the members demonstrated continuous prairie points. We started with a piece of fabric that was 8" wide and 21 " long. We ironed a crease down the middle lengthways, then marked off sections and cut and folded and Voila! -- we had prairie points. It was pretty easy and fun to learn something new. I googled continuous prairie points and found a really good tutorial, if you are interested.
To make two color points, we started with two fabrics, both were 21" long and 4.5" long. We sewed them together along the long edge and used the seam as the fold line. From there the process was the same, except the points were alternating colors.
The solid color was a little easier to work with since there was no bulk at the fold like the two color one, but overall, I think it is a pretty nifty technique. The person who showed us how to make the points, also had a quilt that she was finishing that used the technique. Hers were all one fabric and came out great.
