Sadly I don't think there is anything you can do to save the points unless you made each element larger from the beginning. I do that sometimes so I don't lose my points. As for the batting I use 80/20 blend for summer quilts or for someone who is warm all the time. You don't by any chance have enough fabric to redo your blocks or maybe you could take it down to 11 1/2" block? I have had to do this when the fabric frayed more than I thought it would. Good luck with your dilemma! I actually think with the hourglass unit and the hst cutting it down will probably be your best bet.
