This is the Fractions pattern I have. It's by Mountainpeek creations. It's on the right on this site. It's similar to a rail fence but the inner "rails" are made of two pieces of fabric instead on one.
I first saw it in a quilt shop and it was made up in pastels for a baby quilt. Looks entirely different that the photo on the pattern.

Edit: I just clicked on the above link and it didn't take me to the page I thought it would. Enter "fractions" in the search box and it will bring it up.
