Interlocked Squares - Week 31

I wasn't going to post a block this week because the heat and humidity have left me light headed.  But we are getting a little bit of rain today - a tiny little bit, so I will post a block called 'Interlocked Squares'.  It's only 6 inches square, but the construction of the seams might be a bit challenging.

Are you enjoying a long weekend where you are?  Enjoy it if you do!
