So many HST!!!!! I draw the line as I go. I draw corner to corner and then sew on either side, as a chain. Turn cut apart and repeat. Yes it is tedious. But if you cut first then you are sewing on the bias and triangle may stretch making quit a mess. I just made 102(204) and thought that was a pain. Take your time and divide squares into piles, sew all in the pile, do complete process on that pile and then on to the next. Should take same amount of time but is not as intimidating.
