I only found out about this a couple of days ago. I've cut everything out and finished sewing the HSTs last night, but still need to press and trim, so I'm definitely going to be working from behind. My plan is to finish by Friday. I'm using scraps, so didn't have quite enough of everything to make matching 2-1/2" squares, but after I see the clue that uses them, I'll decide what I need to do to fill in.
