I do. For many years I've been doing the HST by adding the 7/8" to the finished size, and then sewing that 'scant' 1/4" along both sides of the drawn diagonal line. But, the square always seemed to turn out sort of wonky, and then when set into the overall block, the blocks were always too small. So, now, I add a whole inch to the finished size of the square (so, for a 2" finished HST, I cut 3" squares) -- then I square up ALL 4 sides (I have this nifty little small square that's 2 1/2" - the size I make the most) and now my finished blocks are always Perfect! Which then, of course, makes the entire quilt perfect.
