Abstract Thursday 64 - Squares in Architecture

A bit of an emergency blip today.  Have been at the craft shop all day, as someone had booked a session with me to learn Parchment work, after the card class had finished.  Therefore, of course I was caught up in rush hour traffic on the way home, so did not have time to stop at the place I had decided would be ideal for today's Abstract Thursday challenge, hosted by youoregon1.  This is a section of a row of square windows at the top of a building I can see from the bedroom window.  It is SOOC, but using the sepia effect setting to soften the shot a bit.  I hope this will fit the challenge.
