Could you switch from binder to Circa notebooks or folders with fasteners which hold 3 holes punched letter size paper or sheet protectors?
I was thinking of switching to Circa (too expensive) but I have been using poly folders with fastener for a number of years and it really lighten the load.
I also use Large Clear Organizer Pouches to hold the folders and loose paperwork associated with the same topic.
Large Clear Organizer Pouches are real space and time savers, they fit the Large Cafe Bag and larger bags.
.PS: I have a bit of a poly folders and Large Clear Organizer Pouches collection.
I color code topics.
