Beautiful amma and thanks so much for the tute on 'how to mess up a block then rescue it so it looks EVEN MORE lovely than was intended'! :D
PS - re seam ripping when PPing - I had to rip a seam in Joy's block I made - I positioned the piece wrong so that when I flipped it didn't extend to the edge - and I remembered having seen a video somewhere on the net of a lady seam ripping with a rotary cutter - you pull the seam apart ever so gently, just enough to give a little tension in the stitch, then nick it with the (sharp!) blade of your cutter; it worked a treat, was really quick and there was no distortion even though the seam was on the bias. I'm sorry, I can't remember where I saw it to give the link but I hope you get the idea from my rambling explanation! :D
