Are you looking for portable storage or permanent (desk type) storage?
I have some pegboard mounted above my desk where I use hooks to hang the CCS templates by group (circles, ovals, etc.) and I punched a small hole in the corner of the measurement sheets to hand them together from another hook. Here is link to a pic in my gallery:

For taking them to crops I use a Memory Mate Case to carry the templates in and I put the measurement sheets in a pocket of my carryall.
