Ok, I'm not sure what size HST you are wanting to finish with. If you need 8 (2inch) finished HST, you would want the starting squares to be 5 3/4" x 5 3/4". So, in other words, start with 7/8" larger than the finished HST should be when making only 2.

8 x 3 inch finished = 7 3/4 x 7 3/4 starting squares
8 x 4 inch finished = 9 3/4 x 9 3/4 starting squares
8 x 5 inch finished = 11 3/4 x 11 3/4 starting squares
8 x 6 inch finished = 13 3/4 x 13 3/4 starting squares

PM me if I can make it more clear. :)

This is how my mind works out the math.

Normally, you take what you want for a finished size (2") and add 7/8" and cut two blocks, mark diagonally, sew on each side and cut to get two squares. I always add and extra 1/8" so I would start with 3" blocks.

In your diagram, you basically have 4 blocks. So 3+3=6 and I would start with a six inch block and follow your instructions.

Finish 3" would be 8" block
Finish 4" would be 10" block

Looks like the formula would be finished x 2 + 2 the way I do it.

And then I would square up.....however, there is a tute on here for making HSTs that I love, and have been using that method...no squaring up! You sew two strips together on both sides, and use a triangle ruler to cut the blocks out. They come out perfect with little waste.
