I have made a couple of those and had the same thoughts as you did...so I put a couple of stitches at the end of each point...seemed to work pretty well too...I also tried cutting the bulk of the material, because I want to incorporate the block into a quilt..That is as far as I have gotten because I had to finish up my son's quilt...but now that's finished maybe I will go and work on it some more..Love your colors...
