New Attraction to an Old Tool

I've been getting re-acquainted with my Easy Angle Ruler.  It has turned out to be a very efficient tool for my half square triangles.  Why have I been keeping it idle in my toolbox?

 Here is a sampling of 24 HST blocks I  made this morning. I didn't have to draw a diagonal line down the center of a square, stitch on both sides of the line and cut in half..... and I didn't have to do more trimming down to size at the finish!  When pressed open, they were the correct size.  I checked!

I think I'm trotting off to make another batch!  See ya soon.
