I do mine similar to the previous post by danstamps54. The "problem" with creating your own album page is that you can't get many more than 4 or 5 cut squares to a page.
I did this merely as an example just to show how I set up a sample page:

Frankly, I only set this up intending to print some pages in the future (I haven't done it yet) because if you do your own album pages, you'd have to set up different size spaces for the older CDS postmarks versus the spray-on ink jet cancels. I also plan to use a similar basic format for my collection of envelope cut squares and postage meters, etc. The problem is that with only 4 or 5 examples to a page, the number of pages needed to properly display them all will get quite large very quickly, assuming you want to write some sort of a narrative for each item.
On the other hand, if all you're doing is displaying the cut squares without any narrative, the Vario page approach is probably the better alternative as you can fit many more to a page.
