Pay attention to the order in which the HST and block is sewn together.....that it what gives you the extra 1/4"
on the ends for the final 1/4" to trim out the block. Good luck!
For instance, notice when she sews the top three pieces together; when she flips them over to press, there's 1/4" remaining beyond the points on top....
Try one sewing it like she does.....you might be over thinking it and thinking it won't come out right; but after the bottom is sewed to the top portion, and the two side pieces are sewn together, that should leave 1/4 all around for you...I hope anyway! Best of luck.
