Would that qualify as right side up or upside down?

I am loving half square triangles lately!  Right now I am staring at my Sheets and Shirts Quilt and dreaming of the next quilt I can make with half squares.  

But it got me thinking...

How do you see HST's?  

I see them this way -- with the pattern in the bottom left corner.

While others see them the opposite way as me, with the printed fabric in the top right corner.

Now I'm not suggesting that there is a right or a wrong way of doing things, just a curious observation on my part.

1. Half Square Triangle Quilt, 2. seeing red quilt front, 3. My first queen size quilt ..., 4. Modern Swappers_Quilt, 5. Citrus HST Quilt, 6. Sheets and Shirts HST Quilt, 7. HST-3, 8. I Dream of Triangles

 So, in the interest of scientific discovery -- How do you see HST's? 

a). Bottom Left corner or  b). Top Right corner

Just wondering...
