Hi,
I serged the hem and sleeve edges and turned them up and top stitched about 1/2 inch from edge. Both square's seams were matched. My small square was approximately half the size of the other. I would imagine if they were not you would get a longer or shorter "V".

The sides were sewn from bottom to top almost to the sleeve edge. This was to allow me to get into that corner to cut away the excess for my sleeve length.

The sides were also serged. I had to clip at the armpits to make them less bulky.

Hope this helps.

Hi,

After my first muslin I too resorted to my algebra. The smaller square from corner to corner should be half the hip measurements. I added for ease and seams (24 inches). That measurement represented the hypotenuse. To get the square sides I divided the hypotenuse by 1.41421 (square root of 2)=(17 inches)based on this formula:

Perimeter of square triangle
Formula n(side1) + n(side 2) + n √2 . (hypotenuse)

To clarify, I already knew the hypotenuse so the sides = that divided by 1.41421.

For the larger square I measured myself from the desired front hip length around my shoulder at the neck edge to the desired back hip length (50 inches). I also added a little extra for hem. Using the same formula I determined the large square sides (35 inches).

To finish my shirt I designed a square neck line with facings.

It was worth doing two muslins to get the pleasing results.
