Rail Baby

Pair up a light and dark slice.  Turn every other block with either a dark on top or on the left, and you have a big chunky zig-zaggy rail.  I plan to use lots of the leftovers this way. 

For this little baby, I just happened to have 16 each of the two duck prints.  And in less than an hour, with a little border,  I had a sweet quilt top.
