Tokyo Subway Quilt - 3/5 complete

I took a break from the SuperNova Quilt-a-long on Saturday to do some more work on my Tokyo Subway Quilt.  I was able to get blocks 13, 14, and 15 completed.  Unfortunately I misplaced block 13 from the last time I worked on it and had to re-do it!  Hopefully I won't run out of fabric from those particular subway lines!
