Found this in log cabin modern section of pinterest.com:
http://quiltinspiration.blogspot.com...shots-and.html
It has more than two strips but is wonky. Not what you described, but nice quilt!
Your best bet to finding it is to go on pinterest, put log cabin in search, (several sections came up, so search each section), sit back and enjoy some eye candy. Hope you find it. Good luck.
