I organized all of my miscellaneous personal-sized inserts today. And these are just the ones I DON'T use regularly. The ones I use regularly are kept in two PlanAhead binders. All of the ones in this box are inserts that either came pre-loaded with new Filofaxes, or they are ones that I purchased and then discarded. However, I save them because (a) I might want to sell them as part of a Filofax, or give them away and (b) I might think one day that I really NEED a particular format again for some new purpose. This way, even if they are out of date, I have them and can play around with them and decide whether or not I really NEED to re-purchase with the current date.
P.S. I use Chrome and I have to left-click on the image once, then right-click on the image and select 'open image in new tab', go to that tab and then click on THAT image in order to make it larger and more legible. So, five clicks (counting the jump to the new tab) to make it big.
