Squaring Up

I trimmed all of my HST's...

and this is the pile of scraps I got.  They look fantastic, but I'm wondering if it is all worth it.  It took almost three hours to square up all 96 of these babies.  I've never done something with so many of these before that I squared up before using in a quilt, and it really took forever.  I'm thinking about trying this method some time, but I'm not sure if I'll get the accuracy I want.  Either way, these are done, and ready to start arranging on the design wall.
