I'll just tell you what I'd do. Rather than trying to repair a system that needs lots of fixing, it's nearly always better to start over with a simpler system. With these kinds of stamp pages, using the standard stamp pages others use and which are easily available and fairly cheap and which have many binder options available, would be the way to go. In other words, scrap the small pages you have which you're trying to cope with in favor of some actual Vario pages.
You can buy packets of Vario pages very inexpensively on
Amazon and
ebay that will work out to around 70 cents a page or so. And you can use any of the Lighthouse binders that fit them. The Vario F binder is really nice, but any sturdy three-ring binder will work if you need to save money.
Problem solved, and you won't have your page and binder problem anymore. Good luck whatever you do!
