World's Fastest Rail Fence:

What you need:
5 - 2.5" x WOF strips of green print (center strips)
10 - 2.5" x WOF strips of white and tan print (inner strips)
10 - 2.5" x WOF strips of brown print (outer strips)

What you do:

Sew one tan strip to each of your green strips. Press.

Sew the other tan strip to the other side of the green strip. Make sure to sew it the same way that you sewed the first one on (ie. green on top vs. tan on top -- this will help prevent you from ending up with a wonky strip set). Press.

Sew brown strips to the outside of your strip sets as above. Press.

Your strip set should end up 10.5" wide. You should make 5 strip sets.
Cross cut each of the 5 strip sets into 4 blocks each at 10.5" wide.

NOTE: cutting 4 squares out of your strip set WILL BE TIGHT -- your fabric will need to be at least 42" wide. If you can only get three 10.5" blocks per strip set, you will need seven strip sets instead of 5.

If necessary, make sure that your cuts are perpendicular to the seams of the strips by squaring up the end before you cut.

You should end up with 20 blocks that are 10.5" square. Sew together in an array of 4 blocks by 5 blocks. Layer with backing and batting and quilt as desired.
