I had a hard time grasping the sewing on point, until one day I looked at the quilt sideways (think as bias) and realized, the blocks are sewn together as regular rows first, then turned to the side to make them on point. I don't like setting triangles, so will sew an extra solid block at the end of the shorter rows, then trim it off after everything is sewn together to make the sides even. I know....clear as mud. Quilting is all about figuring out what works for you, not necessarily, always the "right" way to do it.
