There is a book called "Sew Simple pineapple " by Karin Hellaby that is exactly what you're looking for. I taught a class on this technique and it's quick and easy. The only difference I found between this and a traditional pineapple block, is that in this one, the size of the side pieces increases as you get out from the center.. In a traditional pineapple block, the blades are all the same width.
