Organizer Cubbies for Fabric

I made the Pottery Barn knock off cubby wall organizer for my craft room to store my smaller pieces of fabric.  I modified the dimensions from the plan to fit the specific area it would hang, it ended up being wider and not a square.  I also used half of a 4x8' 3/4" MDF sheet cut 6" tall rather than 1x6 boards.  I also made 14 staggered cubbies rather than the 25 so they could be larger for my fabric storage, and it made it so each divider could be nailed from the top and bottom.   I also was lazy and didn't add a back to it, so you could see the wall if the cubbies weren't full.
