Re: Awkward shaped closet
A cardboard template would be the way to go, but dont try to cut the template exactly, just find your corners and any obstacles that may be there. From there, you lay your template down and use a square from the wide side to locate the narrow side corner points. Then you measure from the point to this line to know what angle to cut your ends at. Make sense? This way, you're not trying to figure out complicated angles, you are simple measuring and scribing a line from point A to point B and cutting this line.
Make sure that you secure the brackets to framing and attach the shelves to the brackets, as shelves of this geometry tend to tip forward.
